Siganidae
Siganidae, the rabbitfishes, are a small family of ray-finned fishes in the order Perciformes. The only extant genus is '' Siganus'', the rabbitfish and spinefoot. However, a number of genera are known from fossils. The extant species are marine fish found in the Indo-Pacific and eastern Mediterranean. They are important foodfishes and some are popular in the aquarium trade. Taxonomy The Siganidae was first formally described as a family in 1837 by the Scottish naval surgeon, naturalist and arctic explorer Sir John Richardson. The genus ''Siganus'' was described in 1775 by the Danish zoologist Johan Christian Fabricius with ''Siganus rivulatus'', a species also described by Fabricius in 1775, designated as the type species. The description was based on notes taken by the naturalist Peter Forsskål when he was on the Danish Arabia expedition (1761–67) and was published in Carsten Niebuhr's ''Descriptiones animalium avium, amphibiorum, piscium, insectorum, vermium; quae in it ...

Siganus Rivulatus
''Siganus rivulatus'', the marbled spinefoot, rivulated rabbitfish or surf parrotfish, is a gregarious, largely herbivorous ray-finned fish of the family Siganidae. Its natural range encompasses the western Indian Ocean and the Red Sea from where it colonised the Mediterranean Sea by Lessepsian migration through the Suez Canal. It is the type species of the genus '' Siganus''. Naming and taxonomy The generic name is new Latin derived from the Arabic ''sijan'' which is equivalent to the English "rabbitfish", the specific name ''rivulatus'' refers to the irregular streaking. It is the type species of the genus ''Siganus'' and therefore of the monogeneric family Siganidae too. ''S. rivulatus'' was named by the Swedish zoologist Peter Forsskål and published posthumously in the book ''Descriptiones animalium, Flora Aegyptiaco-Arabica'', which was edited and published in 1775 by his friend Carsten Niebuhr. The specific name rivulatus means “rivulated”, which in turn means “irre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthuriformes Families
Acanthuriformes is a large, diverse order of mostly marine ray-finned fishes, part of the Percomorpha clade. In the past, members of this clade were placed in the suborders Acanthuroidea and Percoidea of the order Perciformes, but this treatment is now considered paraphyletic. This order contains many of the iconic tropical reef fish groups, such as surgeonfish, marine angelfish, butterflyfish, rabbitfish, grunts, and snappers. It also contains widespread, economically important food and sport fishes, such as drums, temperate basses, and porgies. The only pelagic member of the group is the louvar. Classification The following classification is based on Eschmeyer's Catalog of Fishes (2025): * Order Acanthuriformes ** Family Gerreidae Bleeker, 1859 (mojarras) ** Family Sillaginidae Richardson, 1846 (sillagos) ** Family Moronidae Jordan & Evermann, 1896 (temperate basses) ** Family Drepaneidae Gill, 1872 (sicklefishes) ** Family Ephippidae Bleeker, 1859 (spadefishes & ...

Eupercaria
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant vertebrates. Evolution Percomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous-Paleogene boundary ago. The oldest known percomorph fossils are of the early tetraodontiforms '' Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slovenia. A higher diversity of early percomorphs is also known from the Campanian of Nardò, Italy, and these also show some level of diversification into modern orders, with representatives ...

Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siganoidea
Siganoidea is a superfamily belonging to the suborder Percoidei which in turn is the largest suborder of the order Perciformes. It contains two families of largely Indo-Pacific distribution. Taxonomy Siganoidea is recognised by the 5th edition of the Fishes of the World as a superfamily within the Percoidei. Families The two families placed in the Siganoidea are: * Scatophagidae Gill, 1883 * Siganidae Richardson, 1837 Molecular studies Molecular analyses suggest that these families are closer to the surgeonfishes than to other Percoidei and place these families in the order Acanthuriformes. Other workers have suggested that the two families are among those stated as ''incertae sedis'' with the series Eupercaria Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish) known from both marine and fresh .... Reference ...

Peter Forsskål
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Sweden, Swedish exploration, explorer, oriental studies, orientalist, natural history, naturalist, and an Apostles of Linnaeus, apostle of Carl Linnaeus. Early life Forsskål was born in Helsinki, now in Finland but then a part of Sweden, where his father, the priest , was serving as a Lutheran clergyman, but the family moved to Sweden in 1741 when the father was appointed to the parish of :sv:Tegelsmora församling, Tegelsmora in Uppland and the Archbishop of Uppsala, archdiocese of Uppsala. As was common at the time, he enrolled at Uppsala University at a young age in 1742, but returned home for some time and, after studies on his own, rematriculated in Uppsala in 1751, where he completed a Theology, theological degree the same year. Linnaeus's disciple In Uppsala Forsskål was one of the students of Carl Linnaeus, Linnaeus, but appare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incertae Sedis
or is a term used for a taxonomy (biology), taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by (of uncertain family), (of uncertain suborder), (of uncertain order) and similar terms. Examples * The fossil plant ''Paradinandra, Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus (fossil), Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Boc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishes Of The World
''Fishes of the World'' is a standard reference for the systematics of fishes. It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family is given at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, though the book does generally not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not contain any color illustrations. The fourth edition was the first to inco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. 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 is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Superfamily (biology)
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or '' Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, family, order, class, phylum, kingdom, and domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and thCode for Viruses require them. However, absolute ranks are not r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
