105-680: A highly contested zone between the Imagawa clan based in Suruga Province and various local warlords, who built a number of fortifications in the area, including Yoshida Castle . The rising power of the Matsudaira clan and its alliance with Oda Nobunaga eventually neutralized the threat posed by the Imagawa, and the area became part of the holdings of Tokugawa Ieyasu . Following the Battle of Odawara in 1590, Toyotomi Hideyoshi ordered

140-456: A round of consolidation in May 1906, the town of Fukagawa was created, and the remaining number of villages was reduced from 33 to 10. Toyohashi was also raised to city status on August 1, 1906. Toyohashi annexed two neighboring villages in 1932, leaving the district with three towns and eight villages.

During the Muromachi period , the Isshiki clan rose to prominence, but after

350-625: Is possible to tell male turtles from female turtles by their long tails with a cloacal opening near the tip. Adult female sea turtles have shorter tails, with a cloacal opening near the base. Hatchling and sub-adult turtles do not exhibit sexual dimorphism ; it is not possible to determine their sex by looking at them. In general, sea turtles have a more fusiform body plan than their terrestrial or freshwater counterparts. This tapering at both ends reduces volume and means that sea turtles cannot retract their head and limbs into their shells for protection, unlike many other turtles and tortoises. However,

385-466: Is the smallest sea turtle species, to 120 cm (3.9 ft) long in the case of the green turtle, the second largest. The skulls of sea turtles have cheek regions that are enclosed in bone. Although this condition appears to resemble that found in the earliest known fossil reptiles (anapsids), it is possible it is a more recently evolved trait in sea turtles, placing them outside the anapsids. Sea turtles, along with other turtles and tortoises, are part of

Sea turtles can be categorized as hard-shelled ( cheloniid ) or leathery-shelled ( dermochelyid ). The only dermochelyid species of sea turtle is the leatherback. For each of the seven species of sea turtles, females and males are the same size. As adults, it

490-426: The Meiji Restoration , the area was merged into Aichi Prefecture. In the cadastral reforms of the early Meiji period, on October 1, 1889, Atsumi District was divided into the town of Toyohashi and 32 villages (35 villages by 1891 due to reorganization). The village of Tahara was raised to town status on October 3, 1892, followed by the village of Okawa on June 23, 1893, and the village of Fukue on February 22, 1897. In

735-566: The concurrent giant protostegids such as Archelon and Protostega as one of the largest turtles to ever exist. Unlike the protostegids, which have an uncertain relationship to modern sea turtles, Leviathanochelys is thought to be a true sea turtle of the superfamily Chelonioidea. Sea turtles' limbs and brains have evolved to adapt to their diets. Their limbs originally evolved for locomotion, but more recently evolved to aid them in feeding. They use their limbs to hold, swipe, and forage their food. This helps them eat more efficiently. Below

A lineage of unrelated marine testudines, the pleurodire (side-necked) bothremydids , also survived well into the Cenozoic. Other pleurodires are also thought to have lived at sea, such as Araripemys and extinct pelomedusids . Modern sea turtles are not descended from more than one of the groups of sea-going turtles that have existed in

875-561: The lineage ( Panchelonioidea ) leading to modern sea turtles was possibly Desmatochelys padillai from the Early Cretaceous. Desmatochelys was a protostegid , a lineage that would later give rise to some very large species but went extinct at the end of the Cretaceous. Presently thought to be outside the crown group that contains modern sea turtles (Chelonioidea), the exact relationships of protostegids to modern sea turtles are still debated due to their primitive morphology; they may be
