40-473: See text The Scorpaeniformes / s k ɔːr ˈ p iː n ɪ f ɔːr m iː z / are a diverse order of ray-finned fish , including the lionfishes and sculpins, but have also been called the Scleroparei . It is one of the five largest orders of bony fishes by number of species, with over 1,320. They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay:

80-461: A cohors (plural cohortes ). Some of the plant families still retain the names of Linnaean "natural orders" or even the names of pre-Linnaean natural groups recognized by Linnaeus as orders in his natural classification (e.g. Palmae or Labiatae ). Such names are known as descriptive family names. In the field of zoology , the Linnaean orders were used more consistently. That is,

120-407: A backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the pre operculum , to which it is connected in most species. Scorpaeniform fishes are carnivorous , mostly feeding on crustaceans and on smaller fish. Most species live on the sea bottom in relatively shallow waters, although species are known from deep water, from

160-570: A distinct rank of biological classification having its own distinctive name (and not just called a higher genus ( genus summum )) was first introduced by the German botanist Augustus Quirinus Rivinus in his classification of plants that appeared in a series of treatises in the 1690s. Carl Linnaeus was the first to apply it consistently to the division of all three kingdoms of nature (then minerals , plants , and animals ) in his Systema Naturae (1735, 1st. Ed.). For plants, Linnaeus' orders in

200-692: A homonymy usually produces the same problems as if there were no rules: conflicts between entirely independent and unconnected groups of taxonomists working in different animal groups. Very often the Commission must be asked to take a decision. Examples: For names above the superfamily level, the principle of homonymy does not apply. Examples: Family-rank names and genus-rank names cannot be homonyms of one another, even if identical. Example: Animal, plant, and fungi nomenclature are entirely independent from each other. The most evident shortcoming of this situation (for their use in biodiversity informatics )

240-407: Is decided first by applying the code directly, and not by reference to precedent. The code is also retroactive or retrospective , which means that previous editions of the code, or previous other rules and conventions have no force any more today, and the nomenclatural acts published earlier must be evaluated only under the present edition of the code. In cases of disputes a case can be brought to

280-655: Is not settled; accounts range from 26 to 35 families. The 5th edition of Fishes of the World classifies the order as follows: Order Scorpaeniformes This classification is not settled, however, and some authorities classify these groupings largely within the Order Perciformes as the suborders Scorpaenoidei, Platycephaloidei, Triglioidei and Cottoidei, Cottodei including the infraorders Anoplopomatales, Zoarcales, Gasterosteales, Zaniolepidoales, Hexagrammales and Cottales. These infraorders largely correspond with

320-431: Is that the same generic name can be used simultaneously for animals and plants. For this kind of homonym the expression "hemihomonym" is sometimes used. Far more than 1000 such names are known. Examples: This is the principle that each nominal taxon in the family group, genus group, or species group has—actually or potentially—a name-bearing type fixed that provides the objective standard of reference that determines what

360-539: Is the presence of spine-bearing plate on the armored sea robins which is absent in the sea robins family. The second group of the Scorpaenoidei suborder is the scorpionfishes, which according to Minouri Ishida's work in 1994 and recent studies, have twelve families. The scorpionfishes are very dynamic in size with the smallest one having a range of 2–3 cm, while the largest have a length of approximately 100 cm. The division of Scorpaeniformes into families

400-405: Is the principle that in cases of conflicts between simultaneously published divergent acts, the first subsequent author can decide which has precedence. It supplements the principle of priority , which states that the first published name takes precedence. The principle of the first reviser deals with situations that cannot be resolved by priority. These items may be two or more different names for

440-579: Is the principle that the correct formal scientific name for an animal taxon , the valid name , correct to use, is the oldest available name that applies to it. It is the most important principle—the fundamental guiding precept that preserves zoological nomenclature stability. It was first formulated in 1842 by a committee appointed by the British Association to consider the rules of zoological nomenclature. Hugh Edwin Strickland wrote

480-530: Is usually the first-published name; any later name with the same spelling (a homonym ) is barred from being used. The principles of priority and first reviser apply here. For family-group names the termination (which is rank-bound) is not taken into account. Genera are homonyms only if exactly the same — a one-letter difference is enough to distinguish them. Examples: The following are not homonyms of Argus : The following names are not homonyms of each other: Some spelling variants are explicitly defined by

520-533: Is usually written with a capital letter. For some groups of organisms, their orders may follow consistent naming schemes . Orders of plants , fungi , and algae use the suffix -ales (e.g. Dictyotales ). Orders of birds and fishes use the Latin suffix -iformes meaning 'having the form of' (e.g. Passeriformes ), but orders of mammals and invertebrates are not so consistent (e.g. Artiodactyla , Actiniaria , Primates ). For some clades covered by

560-475: The Code as being homonyms. Otherwise the one-letter difference rule applies. In species, primary homonyms are those with the same genus and same species in their original combination. The difference between a junior primary homonym and a subsequent use of a name is undefined, but it is commonly accepted that if the name referred to another species or form, gave a description, and if there is in addition no evidence

600-528: The International Code of Zoological Nomenclature , several additional classifications are sometimes used, although not all of these are officially recognized. In their 1997 classification of mammals , McKenna and Bell used two extra levels between superorder and order: grandorder and mirorder . Michael Novacek (1986) inserted them at the same position. Michael Benton (2005) inserted them between superorder and magnorder instead. This position

640-815: The Systema Naturae and the Species Plantarum were strictly artificial, introduced to subdivide the artificial classes into more comprehensible smaller groups. When the word ordo was first consistently used for natural units of plants, in 19th-century works such as the Prodromus Systematis Naturalis Regni Vegetabilis of Augustin Pyramus de Candolle and the Genera Plantarum of Bentham & Hooker, it indicated taxa that are now given

680-612: The superfamilies in the Cottoidei set out in the 5th edition of Fishes of the World. Order (biology) What does and does not belong to each order is determined by a taxonomist , as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order

720-409: The acronym "ICZN"). The rules principally regulate: Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature . This implies that animals can have the same generic names as plants (e.g. there is a genus Abronia in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in

760-424: The author knew that the name was previously used, it is considered as a junior homonym. Example: Typically, junior primary homonyms are permanently invalid, but some are treated as valid if the junior and senior homonyms have been in separate genera after 1899 (Art. 57.2.1, Art. 23.9). Examples: Secondary homonyms occur when taxa with the same specific name but different original genera are later classified in

800-521: The code may be deemed simply "unavailable" if it fails to meet certain criteria, or fall entirely out of the province of science (e.g., the "scientific name" for the Loch Ness Monster ). The rules in the code determine which available names are valid for any taxon in the family group, genus group, and species group. It has additional (but more limited) provisions on names in higher ranks . The code recognizes no case law . Any dispute

840-441: The commission who has the right to publish a final decision. In regulating the names of animals it holds by six central principles, which were first set out (as principles) in the third edition of the code (1985): This is the principle that the scientific name of a species, and not of a taxon at any other rank, is a combination of two names; the use of a trinomen for the name of a subspecies and of uninominal names for taxa above

880-408: The committee's report. Examples: There are over 2 million junior synonyms recorded in zoology, primarily at the species level. The principle of coordination is that within the family group, genus group and species group, a name established for a taxon at any rank in the group is simultaneously established with the same author and date for taxa based on the same name-bearing type at other ranks in

920-437: The corresponding group. In other words, publishing a new zoological name automatically and simultaneously establishes all corresponding names in the relevant other ranks with the same type. In the species-group, publishing a species name (the binomen ) Giraffa camelopardalis Linnaeus, 1758 also establishes the subspecies name (the trinomen ) Giraffa camelopardalis camelopardalis Linnaeus, 1758 . The same applies to

960-454: The midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral and caudal fins . Most species are less than 30 cm (12 in) in length, but the full size range of the order varies from the velvetfishes belonging to the family Aploactinidae, which can be just 2 cm (0.79 in) long as adults, to the skilfish ( Erilepis zonifer ), which can reach 183 cm (6.00 ft) in total length . One of

1000-426: The name of a subspecies; this establishes the corresponding species name. In the genus-group, similarly, publishing the name of a genus also establishes the corresponding name of a subgenus (or vice versa): genus Giraffa Linnaeus, 1758 and subgenus Giraffa ( Giraffa ) Linnaeus, 1758 . In the family-group, publication of the name of a family, subfamily, superfamily (or any other such rank) also establishes

1040-425: The names in all the other ranks in the family group (family Giraffidae, superfamily Giraffoidea, subfamily Giraffinae). Author citations for such names (for example a subgenus) are the same as for the name actually published (for example a genus). It is immaterial if there is an actual taxon to which the automatically established name applies; if ever such a taxon is recognised, there is a name available for it. This

1080-419: The naming of all animals, except where taxonomic judgment dictates otherwise. The code is meant to guide only the nomenclature of animals, while leaving zoologists freedom in classifying new taxa . In other words, while species concepts (and thus the definition of species) are arbitrary to some degree, the rules for names are not. The code applies only to names. A new animal name published without adherence to

1120-708: The orders in the zoology part of the Systema Naturae refer to natural groups. Some of his ordinal names are still in use, e.g. Lepidoptera (moths and butterflies) and Diptera (flies, mosquitoes, midges, and gnats). In virology , the International Committee on Taxonomy of Viruses 's virus classification includes fifteen taxomomic ranks to be applied for viruses , viroids and satellite nucleic acids : realm , subrealm , kingdom , subkingdom, phylum , subphylum , class, subclass, order, suborder, family, subfamily , genus, subgenus , and species. There are currently fourteen viral orders, each ending in

1160-564: The precursor of the currently used International Code of Nomenclature for algae, fungi, and plants . In the first international Rules of botanical nomenclature from the International Botanical Congress of 1905, the word family ( familia ) was assigned to the rank indicated by the French famille , while order ( ordo ) was reserved for a higher rank, for what in the 19th century had often been named

1200-502: The rank of family (see ordo naturalis , ' natural order '). In French botanical publications, from Michel Adanson 's Familles naturelles des plantes (1763) and until the end of the 19th century, the word famille (plural: familles ) was used as a French equivalent for this Latin ordo . This equivalence was explicitly stated in the Alphonse Pyramus de Candolle 's Lois de la nomenclature botanique (1868),

1240-412: The rare cases where a single zoological species can have two entirely different names at the same time, depending upon whose classification is followed. Example: Article 59.3 states that junior secondary homonyms replaced before 1961 by substitute names are permanently invalid unless the substitute name is itself not in use. Example: Double homonymy (genus and species) may or may not be homonymy in

1280-401: The same genus (Art. 57.3, 59). A secondary homonym may only be a temporary state, as it only applies so long as two species are congeneric. Under a different classification, the two species may no longer be in the same genus, and the junior name can potentially be used again (Art. 59.1), as long as it was not replaced before 1961, in which case it is permanently invalid (Art. 59.3). This is one of

1320-453: The same genus-group or species-group name was published in the same year by the same author. In these cases it is useful to cite the page where the name was established. There are cases where two homonyms were established by the same author in the same year on the same page: Homonyms occur relatively rarely in families (only if generic names are identical or very similar and adding an ending "-idae" produces identical results). Discovering such

1360-456: The same species, the snowy owl . The two names are subjective synonyms. Lönnberg 1931 acted as first reviser, cited both names and selected Strix scandiaca to have precedence. This is the principle that the name of each taxon must be unique. Consequently, a name that is a junior homonym of another name must not be used as a valid name. It means that any one animal name, in one particular spelling, may be used only once (within its group). This

1400-518: The same taxon, two or more names with the same spelling used for different taxa, two or more different spellings of a particular name, etc. In such cases, the first subsequent author who deals with the matter and chooses and publishes the decision in the required manner is the first reviser, and is to be followed. Example: Linnaeus 1758 established Strix scandiaca and Strix noctua (Aves), for which he gave different descriptions and referred to different types, but both taxa later turned out to refer to

1440-452: The species group is in accord with this principle. This means that in the system of nomenclature for animals, the name of a species is composed of a combination of a generic name and a specific name ; together they make a " binomen ". No other rank can have a name composed of two names. Examples: In botanical nomenclature, the equivalent for "binominal nomenclature" is "binary nomenclature" (or sometimes " binomial nomenclature "). This

1480-414: The strict sense: if the genera are homonyms but not the same genus, the same specific names can be used in both groups, because the species are subsequently placed in different genera when the generic homonymy is removed. Example: For disambiguating one genus-group name from its homonym, it is important to cite author and year. Citing the author alone is often not sufficient. Examples: In some cases,

1520-538: The suborders of the Scorpaeniformes is the Scorpaenoidei . This suborder is usually found in the benthic zone, which is the lowest region of any water body like oceans or lakes. There are two groups of the Scorpaenoidei. The sea robins is the first, which are further classified into two families: the sea robins and the armored sea robins. One significant difference between the two families of sea robins

1560-541: The suffix -virales . International Code of Zoological Nomenclature The International Code of Zoological Nomenclature ( ICZN ) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals . It is also informally known as the ICZN Code , for its publisher, the International Commission on Zoological Nomenclature (which shares

1600-418: Was adopted by Systema Naturae 2000 and others. In botany , the ranks of subclass and suborder are secondary ranks pre-defined as respectively above and below the rank of order. Any number of further ranks can be used as long as they are clearly defined. The superorder rank is commonly used, with the ending -anae that was initiated by Armen Takhtajan 's publications from 1966 onwards. The order as
