109-544: The promontory was known as Poseidion ( Ancient Greek : Ποσείδιον ) in Antiquity, indicating that it used to have a shrine dedicated to Poseidon . When the Sinai Peninsula was returned to Egypt, Ras Muhammad was declared for protection from fishing and other human activities. Some of the fishing methods, such as using dynamite and knives were also impacting on the coral reef and the fish populations. In 1983,

218-543: A pitch accent . In Modern Greek, all vowels and consonants are short. Many vowels and diphthongs once pronounced distinctly are pronounced as /i/ ( iotacism ). Some of the stops and glides in diphthongs have become fricatives , and the pitch accent has changed to a stress accent . Many of the changes took place in the Koine Greek period. The writing system of Modern Greek, however, does not reflect all pronunciation changes. The examples below represent Attic Greek in

327-540: A beaked head at the end of a short neck, and paddle-like arms well-adapted for swimming. Adult green turtles grow to 1.5 metres (5 ft) long. The average weight of mature individuals is 68–190 kg (150–419 lb) and the average carapace length is 78–112 cm (31–44 in). They are considered the second largest sea turtle in the United States, after the leatherback sea turtle. Exceptional specimens can weigh 315 kg (694 lb) or even more, with

436-594: A few islands south of Tasmania . Significant nesting grounds are scattered throughout the entire Pacific region, including Mexico , the Hawaiian Islands , the South Pacific , the northern coast of Australia , and Southeast Asia . Major Indian Ocean nesting colonies include India , Pakistan , Sri Lanka and other coastal countries. The turtles can also be found throughout the Indian Ocean ;

545-477: A lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period. They have the same general outline but differ in some of the detail. The only attested dialect from this period is Mycenaean Greek , but its relationship to the historical dialects and

654-419: A lesser degree. Pamphylian Greek , spoken in a small area on the southwestern coast of Anatolia and little preserved in inscriptions, may be either a fifth major dialect group, or it is Mycenaean Greek overlaid by Doric, with a non-Greek native influence. Regarding the speech of the ancient Macedonians diverse theories have been put forward, but the epigraphic activity and the archaeological discoveries in

763-453: A migrating species, their global distribution spans into the open ocean. The differences in mitochondrial DNA more than likely stems from the populations being isolated from each other by the southern tips of both South America and Africa with no warm waters for the green sea turtles to migrate through. The green sea turtle is estimated to inhabit coastal areas of more than 140 countries, with nesting sites in over 80 countries worldwide throughout

872-882: A population or subspecies of the green turtle (instead of a separate species). However, this is possibly a case of political taxonomy. As such the three major international checklists that cover turtles of the world Reptile Database the checklist of Fritz and Havas (2007) and the IUCN Checklist (TTWG 2017) all consider this a junior synonym. Green sea turtles move across three habitat types, depending on their life stage . They lay eggs on beaches. Mature turtles spend most of their time in shallow, coastal waters with lush seagrass beds. Adults frequent inshore bays, lagoons, and shoals with lush seagrass meadows . Entire generations often migrate between one pair of feeding and nesting areas. Green sea turtles, Chelonia mydas , are classified as an aquatic species and are distributed around

981-550: A prefix /e-/, called the augment . This was probably originally a separate word, meaning something like "then", added because tenses in PIE had primarily aspectual meaning. The augment is added to the indicative of the aorist, imperfect, and pluperfect, but not to any of the other forms of the aorist (no other forms of the imperfect and pluperfect exist). The two kinds of augment in Greek are syllabic and quantitative. The syllabic augment

1090-415: A problem with this hypothesis is that some turtles travel thousands of miles to return to their native beaches, and the scents from that area are not likely to travel and be distinguishable from that distance. The second hypothesis is the geomagnetic. This hypothesis states that as it hatches, a young turtle will imprint on the magnetic field of the beach they are born on. This hypothesis strongly correlates to

1199-734: A record number. In addition to sporadic distribution of nesting sites, feeding grounds are much more widely distributed throughout Florida . Important feeding grounds in Florida include Indian River Lagoon , the Florida Keys , Florida Bay , Homosassa , Crystal River , and Cedar Key . Notable locations in South America include secluded beaches in Suriname and French Guiana . In the Southern Atlantic Ocean,

1308-778: A relatively slow growth rate because of the low nutritional value of their diet. Body fat turns green because of the consumed vegetation . This diet shift has an effect on the green turtle's skull morphology. Their serrated jaw helps them chew green and red algae (such as filamentous red alga ( Bostrychia ), red moss ( Caloglossa ), freshwater red algae ( Compsopogon ), lobster horns ( Polysiphonia ), sea lettuce ( Ulva lactuca ), green seaweed ( Gayralia ), and crinkle grass ( Rhizoclonium )) and sea grasses. They also consume large quantities of wetland plants such as Avicennia schaueriana and Sporobolus alterniflorus , which are commonly found in salt marshes. Most adult sea turtles are strictly herbivorous. Only some human beings and

1417-608: A separate historical stage, though its earliest form closely resembles Attic Greek , and its latest form approaches Medieval Greek . There were several regional dialects of Ancient Greek; Attic Greek developed into Koine. Ancient Greek was a pluricentric language , divided into many dialects. The main dialect groups are Attic and Ionic , Aeolic , Arcadocypriot , and Doric , many of them with several subdivisions. Some dialects are found in standardized literary forms in literature , while others are attested only in inscriptions. There are also several historical forms. Homeric Greek

1526-708: A separate species. These two "species" were then united as Chelonia mydas and populations were given subspecies status: C. mydas mydas referred to the originally described population, while C. mydas agassizi referred only to the Pacific population known as the Galápagos green turtle. This subdivision was later determined to be invalid and all species members were then designated Chelonia mydas . The oft-mentioned name C. agassizi remains an invalid junior synonym of C. mydas . The species' common name does not derive from any particular green external coloration of

1635-479: A single claw (as opposed to the hawksbill two), although a second claw is sometimes prominent in young specimens. The carapace of the turtle has various color patterns that change over time. Hatchlings of Chelonia mydas , like those of other marine turtles, have mostly black carapaces and light-colored plastrons. Carapaces of juveniles turn dark brown to olive, while those of mature adults are either entirely brown, spotted or marbled with variegated rays. Underneath,

1744-630: A standard subject of study in educational institutions of the Western world since the Renaissance . This article primarily contains information about the Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period ( c.  300 BC ), Ancient Greek was followed by Koine Greek , which is regarded as

1853-475: A time, but submergence time is much shorter while diving for food or to escape predators. Breath-holding ability is affected by activity and stress, which is why turtles quickly drown in shrimp trawlers and other fishing gear. During the night while sleeping and to protect themselves from potential predators, the adults wedge themselves under rocks below the surface and under ledges in reefs and coastal rocks. Many green sea turtles have been observed in returning to

1962-413: A variety of parasites including barnacles , leeches , protozoans , cestodes , and nematodes . Barnacles attach to the carapace, and leeches to the flippers and skin of the turtles, causing damage to the soft tissues and leading to blood loss. Protozoans, cestodes and nematodes lead to many turtle deaths because of the infections in the liver and intestinal tract they cause. The greatest disease threat to

2071-510: A vowel or /n s r/ ; final stops were lost, as in γάλα "milk", compared with γάλακτος "of milk" (genitive). Ancient Greek of the classical period also differed in both the inventory and distribution of original PIE phonemes due to numerous sound changes, notably the following: The pronunciation of Ancient Greek was very different from that of Modern Greek . Ancient Greek had long and short vowels ; many diphthongs ; double and single consonants; voiced, voiceless, and aspirated stops ; and

2180-465: Is Java's primary religion). In Bali , turtle meat was a prominent feature at ceremonial and religious feasts. Turtles were harvested in the remotest parts of the Indonesian archipelago . Bali has been importing sea turtles since the 1950s, as its own turtle supplies became depleted. The mostly Hindu Balinese do not eat the eggs, but sell them instead to local Muslims . Commercial farms, such as

2289-503: Is a species of large sea turtle of the family Cheloniidae . It is the only species in the genus Chelonia . Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans , but it is also found in the Indian Ocean . The common name refers to the usually green fat found beneath its carapace , due to its diet strictly being seagrass, not to

2398-570: Is a literary form of Archaic Greek (derived primarily from Ionic and Aeolic) used in the epic poems , the Iliad and the Odyssey , and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic and other Classical-era dialects. The origins, early form and development of the Hellenic language family are not well understood because of

2507-456: Is a member of the tribe Cheloniini . A 1993 study clarified the status of genus Chelonia with respect to the other marine turtles. The carnivorous Eretmochelys (hawksbill), Caretta (loggerhead) and Lepidochelys (ridley) were assigned to the tribe Carettini . Herbivorous Chelonia warranted their status as a genus , while Natator (flatback) was further removed from the other genera than previously believed. The species

2616-696: Is a small bay inlet in Ras Mohammed, and Marsa Ghozlani is a very small inlet located across from the park visitors center. The two islands of Tiran and Sanafir were part of the park until sovereignty of the islands was ceded to Saudi Arabia . Ras Muhammad exists at the junction of three plates: the Arabian plate, the African plate, and the Sinai subplate. This, in conjunction with the Northeast motion of

2725-418: Is added to stems beginning with consonants, and simply prefixes e (stems beginning with r , however, add er ). The quantitative augment is added to stems beginning with vowels, and involves lengthening the vowel: Some verbs augment irregularly; the most common variation is e → ei . The irregularity can be explained diachronically by the loss of s between vowels, or that of the letter w , which affected

2834-510: Is an interesting phenomenon. Many researchers believe that sea turtles use a process called imprinting, which is a special type of learning that occurs when turtles first hatch that allows them to recognize their native beach. There are two types of imprinting that are thought to be the reason turtles can find these beaches. The first is the chemical imprinting hypothesis. This hypothesis states that much like salmon, sea turtles are able to use olfactory cues and senses to smell their way home. However,

2943-666: Is called 'East Greek'. Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian Greek had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, as exemplified in the poems of the Boeotian poet Pindar who wrote in Doric with a small Aeolic admixture. Thessalian likewise had come under Northwest Greek influence, though to

3052-488: Is considered a junior synonym of Chelonia mydas as such it is considered as a local variant of the populations of the East Pacific waters and those of other nesting areas. The morphological distinctiveness of the Galápagos green turtle has given rise to the debate, but evidence of taxonomic distinctiveness is best served using the combination of multiple datasets. The two most notable morphological distinctions are

3161-448: Is considered by some linguists to have been closely related to Greek . Among Indo-European branches with living descendants, Greek is often argued to have the closest genetic ties with Armenian (see also Graeco-Armenian ) and Indo-Iranian languages (see Graeco-Aryan ). Ancient Greek differs from Proto-Indo-European (PIE) and other Indo-European languages in certain ways. In phonotactics , ancient Greek words could end only in

3270-439: Is known as natal homing . The males also return to their birthplaces in order to mate. These males that return to their homes know they will be able to find mates because the females born there also return to breed. By doing this, the green sea turtles are able to improve their reproductive success and is why they are willing to expend the energy to travel thousands of miles across the ocean in order to reproduce. Mating behaviour

3379-654: Is known until past the southern tip of Africa in the east and Argentina in the western Atlantic. The major nesting sites can be found on various islands in the Caribbean , along the Atlantic coast of Florida in the United States, the eastern coast of the South American continent and most notably, on isolated North Atlantic islands. In the Caribbean, major nesting sites have been identified on Aves Island ,

3488-489: Is mostly herbivorous . The adults usually inhabit shallow lagoons , feeding mostly on various species of seagrasses . The turtles bite off the tips of the blades of seagrass, which keeps the grass healthy. Like other sea turtles, green sea turtles migrate long distances between feeding grounds and hatching beaches. Many islands worldwide are known as Turtle Island due to green sea turtles nesting on their beaches. Females crawl out on beaches, dig nests, and lay eggs during

3597-556: Is often roughly divided into the following periods: Mycenaean Greek ( c.  1400–1200 BC ), Dark Ages ( c.  1200–800 BC ), the Archaic or Epic period ( c.  800–500 BC ), and the Classical period ( c.  500–300 BC ). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers . It has contributed many words to English vocabulary and has been

3706-417: Is over the binomial classification of the species. At one point the name Chelonia agassizii was applied to this population as a separate species. Analysis of mitochondrial and nuclear DNA of 15 nesting beaches, however, has demonstrated that there is not only no significant distinction of this population but that it would be paraphyletic to recognise it. As such the species name Chelonia agassizzii

3815-440: Is similar to other marine turtles. Female turtles control the process. A few populations practice polyandry , although this does not seem to benefit hatchlings. After mating in the water, the female moves above the beach's high tide line, where she digs a hole 28–56 centimetres (11–22 in) in depth with her hind flippers and deposits her eggs. The hole is then covered up again. Clutch size ranges between 85 and 200, depending on

3924-466: Is simply a color mutation. These facts have led to the debate over binomial separation however due to the significance of the DNA testing results there have been no distinctions made at this time. At a meeting for sea turtle scientists and their collaborators in 2000, the evidence for the taxonomic position of the Galápagos green turtle was reviewed and a majority among the participants supported treating it as

4033-621: The Arabian Sea , both in Ash Sharqiyah , Oman , and along the coast of Karachi , Pakistan . Some specific beaches there, such as Hawke's Bay and Sandspit , are common to both C. mydas and L. olivacea subpopulation. Sandy beaches along Sindh and Balochistan are nesting sites. Some 25 kilometers (16 mi) off the Pakistani coast , Astola island is another nesting beach. The population that has often been known as

4142-658: The Cayman Turtle Farm in the West Indies , once bred them for commercial sale of turtle meat, turtle oil (rendered from the fat), turtle shell, and turtle leather made from the skin. The farm's initial stock was in large part from "doomed" eggs removed from nests threatened by erosion, flooding, or in chemically hostile soil. The farms held as many as 100,000 turtles at any one time. When the international markets were closed by regulations that did not allow even farm-bred turtle products to be exported internationally,

4251-601: The Great Barrier Reef has two genetically distinct populations ; one north and one south. Within the reef, 20 separate locations consisting of small islands and cays were identified as nesting sites for either population of C. mydas . Of these, the most important is on Raine Island . In the Torres Strait there is a large rookery on Bramble Cay . The Coral Sea has nesting areas of world significance. Major nesting sites are common on either side of

4360-663: The Great Barrier Reef in Australia, and the Caribbean Sea . The green sea turtle can generally be found throughout the Atlantic Ocean . Although the species is most abundant in tropical climates, green sea turtles can also be found in temperate climates , and individuals have been spotted as far north as Canada in the western Atlantic, and the Cimbrian peninsular in the east. The subpopulation's southern range

4469-759: The Greek region of Macedonia during the last decades has brought to light documents, among which the first texts written in Macedonian , such as the Pella curse tablet , as Hatzopoulos and other scholars note. Based on the conclusions drawn by several studies and findings such as Pella curse tablet , Emilio Crespo and other scholars suggest that ancient Macedonian was a Northwest Doric dialect , which shares isoglosses with its neighboring Thessalian dialects spoken in northeastern Thessaly . Some have also suggested an Aeolic Greek classification. The Lesbian dialect

4578-547: The Hawaiian Islands first became populated. The turtle symbolizes a navigator that can find his way home time after time. This symbol mirrors the real life of the green Hawaiian turtle as it will swim hundreds of miles to lay its eggs at its own place of birth. Though there are other myths as well, some Hawaiian legends say the honu were the first to guide the Polynesians to the Hawaiian Islands. Hawaiians revere

4687-564: The SS Thistlegorm , located off the coast of Ras Muhammad, is a popular area for divers. The area is home to more than 1,000 species of fish, 40 species of starfish , 25 species of sea urchins , more than 100 species of mollusks and 150 species of crustaceans . Among others, sea turtles , such as the green turtle ( Chelonia mydas ) and the hawksbill turtle ( Eretmochelys imbricata ) appear regularly in Ras Muhammad. On

4796-521: The South Atlantic , C. mydas females create 6,000 to 25,000 nests. They are among the largest green turtles in the world; many are more than 1 metre (3 ft 3 in) in length and weigh up to 300 kilograms (660 lb). Sea turtles spend almost all their lives submerged, but must breathe air for the oxygen needed to meet the demands of vigorous activity. With a single explosive exhalation and rapid inhalation, sea turtles can quickly replace

4905-791: The U.S. Virgin Islands , Puerto Rico , the Dominican Republic , and Costa Rica . In recent years, there are signs of increased nesting in the Cayman Islands. One of the region's most important nesting grounds is in Tortuguero in Costa Rica. In fact, the majority of the Caribbean region's C. mydas population hails from a few beaches in Tortuguero. Within United States waters, minor nesting sites have been noted in

5014-501: The present , future , and imperfect are imperfective in aspect; the aorist , present perfect , pluperfect and future perfect are perfective in aspect. Most tenses display all four moods and three voices, although there is no future subjunctive or imperative. Also, there is no imperfect subjunctive, optative or imperative. The infinitives and participles correspond to the finite combinations of tense, aspect, and voice. The indicative of past tenses adds (conceptually, at least)

5123-1031: The 5th century BC. Ancient pronunciation cannot be reconstructed with certainty, but Greek from the period is well documented, and there is little disagreement among linguists as to the general nature of the sounds that the letters represent. /oː/ raised to [uː] , probably by the 4th century BC. Greek, like all of the older Indo-European languages , is highly inflected. It is highly archaic in its preservation of Proto-Indo-European forms. In ancient Greek, nouns (including proper nouns) have five cases ( nominative , genitive , dative , accusative , and vocative ), three genders ( masculine , feminine , and neuter ), and three numbers (singular, dual , and plural ). Verbs have four moods ( indicative , imperative , subjunctive , and optative ) and three voices (active, middle, and passive ), as well as three persons (first, second, and third) and various other forms. Verbs are conjugated through seven combinations of tenses and aspect (generally simply called "tenses"):

5232-495: The Archaic period of ancient Greek (see Homeric Greek for more details): Μῆνιν ἄειδε, θεά, Πηληϊάδεω Ἀχιλῆος οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε, πολλὰς δ' ἰφθίμους ψυχὰς Ἄϊδι προΐαψεν ἡρώων, αὐτοὺς δὲ ἑλώρια τεῦχε κύνεσσιν οἰωνοῖσί τε πᾶσι· Διὸς δ' ἐτελείετο βουλή· ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.

Local activists also moving some turtle nests to the coast, in the vicinity of the small town of Malena, to save and increase the turtle population in the safe place. Indonesia has a few nesting beaches, one in the Meru Betiri National Reserve in East Java . Off the north-eastern and northern coasts of Australia,

The park was also established to protect against urban sprawl from Sharm El Sheikh and other coastal development. The name literally means "Cape of Muhammad". In this instance, "Ras (Arabic: Head)" means " headland ". It is said that the name arose because the contour of

5668-476: The Galápagos green turtle have been recorded and observed in the Galápagos as far back as the 17th century by William Dampier . Not much attention has been paid to them due to the overwhelming research done on the Galápagos giant tortoises . Only over the last 30 years have extensive studies been performed covering the behaviors of the Galápagos green turtles. Much of the debate that has surrounded them recently

5777-541: The Hawaiian Islands. In the Philippines , green turtles nest in the Turtle Islands along with closely related hawksbill turtles . In December 2007, fishermen using a hulbot-hulbot (a type of fish net ) accidentally caught an 80 kg (180 lb), 93 cm (37 in) long and 82 cm (32 in) wide turtle off Barangay Bolong, Zamboanga City , Philippines . December is breeding season near

About 0.9 hectares of mangrove forest cover a 1.16 km (0.72 mi) shallow channel at the southernmost end of Ras Muhammad peninsula. Near the mangrove and approximately 150 m inland, there are open cracks in the land, caused by earthquakes. One of the cracks is approximately 40 m (130 ft) length and 0.20–1.5 m (0.66–4.9 ft) in width. Within

6104-464: The abundance of sea turtles in the waters around the islands. Many of the earliest visitors came to the Cayman Islands to capture the turtles as a source of fresh meat during long voyages. The green turtle is a national symbol displayed as part of the coat of arms of the Cayman Islands , which also forms part of the national flag of the Cayman Islands . The country's currency uses a turtle as

6213-405: The age of the female. This process takes about an hour to an hour and a half. After the nest is completely covered, she returns to the sea. The female will do this 3 to 5 times in one season. The eggs are round and white, and about 45 mm (1.8 in) in diameter. The hatchlings remain buried for days until they all emerge together at night. The temperature of the nest determines the sex of

6322-436: The air in their lungs. The lungs permit a rapid exchange of oxygen and prevent gases from being trapped during deep dives. Sea turtle blood can deliver oxygen efficiently to body tissues even at the pressures encountered during diving. During routine activity, green and loggerhead turtles dive for about four to five minutes, and surface to breathe for one to three seconds. Turtles can rest or sleep underwater for several hours at

6431-550: The aorist. Following Homer 's practice, the augment is sometimes not made in poetry , especially epic poetry. The augment sometimes substitutes for reduplication; see below. Almost all forms of the perfect, pluperfect, and future perfect reduplicate the initial syllable of the verb stem. (A few irregular forms of perfect do not reduplicate, whereas a handful of irregular aorists reduplicate.) The three types of reduplication are: Irregular duplication can be understood diachronically. For example, lambanō (root lab ) has

6540-419: The augment when it was word-initial. In verbs with a preposition as a prefix, the augment is placed not at the start of the word, but between the preposition and the original verb. For example, προσ(-)βάλλω (I attack) goes to προσ έ βαλoν in the aorist. However compound verbs consisting of a prefix that is not a preposition retain the augment at the start of the word: αὐτο(-)μολῶ goes to ηὐ τομόλησα in

6649-479: The bare open ocean that surround them. These young turtles are rarely seen as they swim in deep, pelagic waters. Green sea turtles typically swim at 2.5–3 km/h (1.6–1.9 mph). As one of the first sea turtle species studied, much of what is known of sea turtle ecology comes from studies of green turtles. The ecology of C. mydas changes drastically with each stage of its life history. Newly emerged hatchlings are carnivorous , pelagic organisms, part of

One standard formulation for the dialects is: West vs. non-West Greek is the strongest-marked and earliest division, with non-West in subsets of Ionic-Attic (or Attic-Ionic) and Aeolic vs. Arcadocypriot, or Aeolic and Arcado-Cypriot vs. Ionic-Attic. Often non-West

The park is situated in the tourist region of the Red Sea Riviera , located 12 km (7.5 mi) from the city of Sharm El Sheikh . The park spans an area of 480 km (190 sq mi), including 135 km (52 sq mi) of surface land area and 345 km (133 sq mi) area over water. Marsa Bareika

6976-403: The color of its carapace, which is olive to black. The dorsoventrally flattened body of C. mydas is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle -like flippers . It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle , C. mydas

7085-425: The considerably smaller adult size and the much darker pigmentation of the carapace, plastron, and extremities. Other distinctions are the curving of the carapace above each hind flipper, the more dome-shaped carapace, and the very long tail of adult males. Three possibilities have arisen from their unique characteristics: agassizii is a separate species from C. mydas , it is a subspecies of green sea turtle, or it

The inland area includes a diversity of desert habitats such as mountains and wadis , gravel and coastal mud plains and sand dunes. The area also plays a role in bird migration , serving as a place of rest and nourishment. Ras Muhammad National Park experiences a very dry climate, with only minimal rainfall during

All the groups were represented by colonies beyond Greece proper as well, and these colonies generally developed local characteristics, often under the influence of settlers or neighbors speaking different Greek dialects. After the conquests of Alexander the Great in the late 4th century BC, a new international dialect known as Koine or Common Greek developed, largely based on Attic Greek , but with influence from other dialects. This dialect slowly replaced most of

These turtles feed in seagrass pastures in the Gulf of California . Green turtles belonging to the distinct Hawaiian subpopulation nest at the protected French Frigate Shoals some 800 kilometers (500 mi) west of

7521-399: The egg in the nest also affects sex-determination. Eggs in the center tend to hatch as females due to the warmer conditions within the nest. Green sea turtles play an essential role in the ecosystem in which they live. In the seagrass beds, the turtles feed on the seagrass by trimming only the top and leaving the roots of the plant. Through their feeding technique, the turtles help to improve

7630-448: The eyes are spherical and adjusted to refraction underwater. Sea turtles have no external ear and only one ear bone, called the columella. With one ear bone, the turtles can hear only low frequency sounds, from 200 to 700 Hz. Sounds can also be detected through vibrations of the head, backbone, and shell. The nose of the turtle has two external openings and connects to the roof of the mouth through internal openings. The lower surface of

7739-461: The females by having a longer tail (visibly extending past the shell) and longer claws on the front flippers. The hatching time and sex of the turtles are determined by the incubation temperature of the nest. Hatchings occur more quickly in nests that are warmer than nests that are in cooler conditions. Warm nesting sites above 30 degrees Celsius favor the development of females, whereas nesting sites below 30 degrees Celsius produce males. The position of

7848-444: The flesh of sea turtles a culinary delicacy, including and especially C. mydas . Particularly for this species, the turtle's fat , cartilage , and flesh, known as calipee , are sought as ingredients for making turtle soup , a popular 19th-century English and American dish. In Java , Indonesia , sea turtle eggs were a popular delicacy. However, the turtle's flesh is regarded as ḥarām or "unclean" under Islamic law ( Islam

7957-411: The globe in warm tropical to subtropical waters. The environmental parameter that limits the distribution of the turtles is ocean temperatures below 7 to 10 degrees Celsius. Within their geographical range, the green sea turtles generally stay near continental and island coastlines. Near the coastlines, the green sea turtles live within shallow bays and protected shores. In these protected shores and bays,

8066-423: The green sea turtle habitats include coral reefs, salt marshes, and nearshore seagrass beds. The coral reefs provide red, brown, and green algae for their diet and give protection from predators and rough storms within the ocean. The salt marshes and seagrass beds contain seaweed and grass vegetation, allowing ample habitat for the sea turtles. Turtles spend most of their first five years in convergence zones within

8175-452: The health and growth of the seagrass beds. The healthy seagrass beds that the turtles provide give habitat and feeding grounds for many species of fish and crustaceans. On the nesting beaches, the green sea turtles provide key nutrients for the ecosystem through their hatched egg shells. In their coral reef habitat, the green sea turtles have a symbiotic interaction with reef fish, including the yellow tang. The yellow tang fish swims along with

8284-561: The historical Dorians . The invasion is known to have displaced population to the later Attic-Ionic regions, who regarded themselves as descendants of the population displaced by or contending with the Dorians. The Greeks of this period believed there were three major divisions of all Greek people – Dorians, Aeolians, and Ionians (including Athenians), each with their own defining and distinctive dialects. Allowing for their oversight of Arcadian, an obscure mountain dialect, and Cypriot, far from

8393-476: The historical circumstances of the times imply that the overall groups already existed in some form. Scholars assume that major Ancient Greek period dialect groups developed not later than 1120 BC, at the time of the Dorian invasions —and that their first appearances as precise alphabetic writing began in the 8th century BC. The invasion would not be "Dorian" unless the invaders had some cultural relationship to

8502-730: The larger sharks feed on C. mydas adults. Specifically, tiger sharks ( Galeocerdo cuvier ) hunt adults in Hawaiian waters. The tiger shark is the main predator of the green turtle as it will prey on green turtles of all sizes. The tiger shark has often been seen feeding on green turtles near their nesting beaches because they are restricted in the area of their nesting beaches and vulnerable to predation. Juveniles and new hatchlings have significantly more predators, including crabs , small marine mammals and shorebirds . Additionally, their eggs are vulnerable to predation by scavengers like red foxes and golden jackals . Green sea turtles have

8611-407: The largest known C. mydas having weighed 395 kg (871 lb) and measured 153 cm (60 in) in carapace length. Anatomically, a few characteristics distinguish the green turtle from the other members of its family. Unlike its close relative the hawksbill turtle , the green turtle's snout is very short and its beak is unhooked. The neck cannot be pulled into the shell. The sheath of

8720-446: The magnetic crystals in their brains. Through these crystals, they can sense the intensity of Earth's magnetic field and are able to make their way back to their nesting grounds or preferred feeding grounds. Natal homing is an animal's ability to return to its birthplace in order to reproduce. Natal homing is found in all species of sea turtles and in other animals such as salmon. How these turtles are able to return to their birthplace

8829-460: The method which sea turtles use to navigate the earth. In order to tolerate the constant heat loss in the water, sea turtles have the ability to shunt blood away from tissues that are tolerant of low oxygen levels toward the heart, brain, and central nervous system. Other mechanisms include basking on warm beaches and producing heat through their activity and movements of their muscles. Basking turtles sometimes look like they are crying because behind

8938-490: The most notable nesting grounds for Chelonia mydas are found on the island of Ascension , hosts 6,000–13,000 turtle nests. In the Pacific , its range reaches as far north as the southern coast of Alaska and as far south as Chile in the east. The turtle's distribution in the western Pacific reaches north to Japan and southern parts of Russia 's Pacific coast, and as far south as the northern tip of New Zealand and

9047-567: The nasal passage has two sets of sensory cells called the Jacobson's organ. The turtle can use this organ to smell by pumping water in and out of its nose. Since green sea turtles migrate long distances during breeding seasons, they have special adaptive systems in order to navigate. In the open ocean, the turtles navigate using wave directions, sun light, and temperatures. The sea turtles also contain an internal magnetic compass. They can detect magnetic information by using magnetic forces acting on

9156-418: The necessary components for their nesting to be successful. These include a sandy beach, easy access for the hatchlings to get to the ocean, the right incubation temperatures, and low probability of predators that may feed on their eggs. Over time these turtles have evolved these tendencies to return to an area that has provided reproductive success for many generations. Their ability to return to their birthplace

9265-810: The night. Later, hatchlings emerge, and scramble into the water. Those that reach maturity may live to 90 years in the wild. C. mydas is listed as endangered by the IUCN and CITES and is protected from exploitation in most countries. It is illegal to collect, harm, or kill them. In addition, many countries have laws and ordinances to protect nesting areas. However, turtles are still in danger due to human activity. In some countries, turtles and their eggs are still hunted for food. Pollution indirectly harms turtles at both population and individual scales. Many turtles die after being caught in fishing nets. In addition, real estate development often causes habitat loss by eliminating nesting beaches. The green sea turtle

9374-469: The ocean. Little is known of the initial life history of newly hatched sea turtles. Juveniles spend three to five years in the open ocean before they settle as still-immature juveniles into their permanent shallow-water lifestyle. It is speculated that they take twenty to fifty years to reach sexual maturity . Individuals live up to eighty years in the wild. It is estimated that only 1% of hatchlings reach sexual maturity. Each year on Ascension Island in

9483-508: The older dialects, although the Doric dialect has survived in the Tsakonian language , which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek . By about the 6th century AD, the Koine had slowly metamorphosed into Medieval Greek . Phrygian is an extinct Indo-European language of West and Central Anatolia , which

9592-563: The open ocean mini nekton . In contrast, immature juveniles and adults are commonly found in seagrass meadows closer inshore as herbivorous grazers. The diet of green turtles changes with age. Juveniles are carnivorous, but as they mature they become omnivorous. Young sea turtles eat fish and their eggs , sea hare eggs, hydrozoans , bryozoans , molluscs , jellyfish , small invertebrates , echinoderms , tunicates , insects , worms , sponges , algae , sea grasses , leaves , tree bark , and crustaceans . Green sea turtles have

9701-487: The perfect stem eilēpha (not * lelēpha ) because it was originally slambanō , with perfect seslēpha , becoming eilēpha through compensatory lengthening. Reduplication is also visible in the present tense stems of certain verbs. These stems add a syllable consisting of the root's initial consonant followed by i . A nasal stop appears after the reduplication in some verbs. The earliest extant examples of ancient Greek writing ( c.  1450 BC ) are in

9810-570: The population's known range. One of the genetic differences between the two subpopulations is the type of mitochondrial DNA found in individual's cells. Individuals from rookeries in the Atlantic Ocean and Mediterranean Sea have a similar type of mitochondrial DNA, and individuals from the Pacific and Indian Oceans have another type of mitochondrial DNA. Their native range includes tropical to subtropical waters along continental coasts and islands between 30°N and 30°S. Since green sea turtles are

9919-403: The same sleeping location night after night. Green sea turtles tend to have good vision, well adapted to a life at sea. The turtles can see many colors, but are most sensitive to light from violet to yellow or wavelengths of 400 to 600 nanometers. They do not see many colors in the orange to red portion of the light spectrum. On land, however, the sea turtles are nearsighted because the lenses in

10028-556: The shoreline. More than 220 species of coral are found in the Ras Muhammad area, 125 of them soft coral . The coral reefs are located 50 to 100 m (160 to 330 ft) below the sea surface, and they have a width of 30 to 50 m (98 to 164 ft) in most places. Though in some spots on the western coast, the coral reef is 8 to 9 km (5.0 to 5.6 mi) wide. Shark Reef and Yolanda Reef are coral reefs hotspots for divers. Other coral reef sites include South Bereika, Marsa Ghozlani, Old Quay, and Shark Observatory. The wreckage of

10137-497: The states of Georgia , North Carolina , and South Carolina . Florida 's east coast is the largest nesting site in the United States. Hutchinson Island in particular is a major nesting area in Florida waters. Florida has several annual nesting periods when local beaches are closed or cordoned off to protect nesting sites. According to Green Sea Turtle Watch, in 2015 more than 37,000 green sea turtle nests were documented in Florida,

10246-481: The surviving farm became primarily a tourist attraction, supporting 11,000 turtles. Initially started as Mariculture Ltd., then Cayman Turtle Farm Ltd and subsequently branded Boatswain's Beach, in 2010 the farm's brandname was changed to Cayman Turtle Farm: Island Wildlife Encounter. Sea turtles are integral to the history and culture of the Cayman Islands . When the islands were first discovered by Christopher Columbus in 1503, he named them "Las Tortugas" because of

10355-517: The syllabic script Linear B . Beginning in the 8th century BC, however, the Greek alphabet became standard, albeit with some variation among dialects. Early texts are written in boustrophedon style, but left-to-right became standard during the classic period. Modern editions of ancient Greek texts are usually written with accents and breathing marks , interword spacing , modern punctuation , and sometimes mixed case , but these were all introduced later. The beginning of Homer 's Iliad exemplifies

10464-405: The tropics, green turtles nest throughout the year, although some subpopulations prefer particular times of the year. In Pakistan , Indian Ocean turtles nest year-round, but prefer the months of July to December. Sea turtles return to the beaches on which they were born to lay their own eggs. The reason for returning to native beaches may be that it guarantees the turtles an environment that has

10573-494: The turtle and feeds on the algae, barnacles, and parasites on its shell and flippers. This species interaction provides food for the yellow tang and provides a necessary cleaning and smoothing of the turtle's shell. This cleaning helps the turtles swim by reducing the amount of drag and improves their health. Historically, the turtles' skin was tanned and used to make handbags , especially in Hawaii . Ancient Chinese considered

10682-577: The turtle population is fibropapilloma , which produces lethal tumor growth on scales, lungs, stomach, and kidneys. Fibropapilloma is caused by a herpesvirus that is transmitted by leeches such as Ozobranchus branchiatus , a species of leech which feeds almost entirely on green sea turtles. Green sea turtles migrate long distances between feeding sites and nesting sites; some swim more than 2,600 kilometres (1,600 mi) to reach their spawning grounds. Beaches in Southeast Asia, India, islands in

10791-469: The turtle's plastron is hued yellow. C. mydas limbs are dark-colored and lined with yellow, and are usually marked with a large dark brown spot in the center of each appendage. The range of the green sea turtle extends throughout tropical and subtropical oceans worldwide. The two major subpopulations are the Atlantic and the eastern Pacific subpopulations. Each population is genetically distinct, with its own set of nesting and feeding grounds within

10900-474: The turtle's upper jaw possesses a denticulated edge, while its lower jaw has stronger, serrated, more defined denticulation. The dorsal surface of the turtle's head has a single pair of prefrontal scales. Its carapace is composed of five central scutes flanked by four pairs of lateral scutes. Underneath, the green turtle has four pairs of inframarginal scutes covering the area between the turtle's plastron and its shell. Mature C. mydas front appendages have only

11009-486: The turtle. Its name comes from the greenish color of the turtles' fat, which is only found in a layer between their inner organs and their shell. As a species found worldwide, the green turtle has many local names. In the Hawaiian language it is called honu , and it is locally known as a symbol of good luck and longevity. Its appearance is that of a typical sea turtle . C. mydas has a dorsoventrally flattened body,

11118-456: The turtles at around the 20–40 day mark. Green Sea Turtles are type 1a, meaning males develop at cooler temperatures while females are produced under hot temperatures. At around 50 to 70 days, the eggs hatch during the night, and the hatchlings instinctively head directly into the water. This is the most dangerous time in a turtle's life. As they walk, predators, such as gulls and crabs , feed on them. A significant percentage never make it to

11227-474: The turtles eye is the lachrymal gland which stores excess salt from the sea water, which then expels through the turtles eye. In the winter months, turtles living at higher latitudes can hibernate for a short period in the mud. Green sea turtles can reach up to 40 miles per hour when swimming, making them the fastest sea turtle. The green sea turtles exhibit sex differences by their development and appearance. As adult turtles, males are easily distinguishable from

11336-550: The watermark in its banknotes. A stylised sea turtle nicknamed "Sir Turtle" is the mascot of the national airline Cayman Airways and is part of the livery of its aircraft. A ki'i pōhaku ( petroglyph ) of a green sea turtle (or honu) can be found on the Big Island of Hawaii in the Pu'u Loa lava fields. The green sea turtle has always held a special meaning for Hawaiians and this petroglyph shows its importance; it may date to when

11445-473: The western Pacific, and Central America are where green sea turtles breed. Mature turtles often return to the exact beach from which they hatched. Females usually mate every two to four years. Males, on the other hand, visit the breeding areas every year, attempting to mate. Mating seasons vary between populations. For most C. mydas in the Caribbean , mating season is from June to September. The French Guiana nesting subpopulation nests from March to June. In

11554-400: The winter. During the summer, temperatures often exceed 40 °C (104 °F) and low temperatures around 27 °C (81 °F). Temperatures are mild during the winter, with daytime high temperatures averaging around 23 °C (73 °F) and low temperatures 14 °C (56 °F). Coral reef, of the fringing and hermatypic types, exist along the coast around Ras Muhammad close to

11663-566: The year. In the United States Atlantic coast, green sea turtles can be found from Texas and north to Massachusetts. In the United States Pacific coast, they have been found from southern California north to the southernmost tip of Alaska. The largest populations of green sea turtles within the United States coastline are in the Hawaiian Islands and Florida . Globally, the largest populations of sea turtles are in

11772-480: Was Aeolic. For example, fragments of the works of the poet Sappho from the island of Lesbos are in Aeolian. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, or to an island. Doric notably had several intermediate divisions as well, into Island Doric (including Cretan Doric ), Southern Peloponnesus Doric (including Laconian ,

11881-517: Was originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Testudo mydas . In 1868, Marie Firmin Bocourt named a particular species of sea turtle Chelonia agassizii , in honor of Swiss-American zoologist Louis Agassiz . This "species" was referred to as the "black sea turtle". Later research determined Bocourt's "black sea turtle" was not genetically distinct from C. mydas , and thus taxonomically not
