Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chordate
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also Bilateral symmetry, bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit Metameric, metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cep ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...

Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...

Symphysanodontidae
''Symphysanodon'', also known as the slopefishes, is a genus of small marine fishes. Most are found in the Indo-Pacific, but three species, ''S. berryi'', ''S. mona'', and ''S. octoactinus'', are found in the Western Atlantic. They are found on rocky reefs at depths of . Traditionally, this genus is the only member of the family Symphysanodontidae, but in 2017 a new species, ''C. aureolateralis'', was placed in its own genus ''Cymatognathus''. Description The largest species of ''Symphysanodon'' can reach in length. Their bodies are slender and compressed, with blunt snouts. They are red, pink, oranges or yellow in colour. The caudal fin is usually distinctively forked. The dorsal fins have 9 dorsal spines and 10 soft rays, whereas the anal fin has three anal spines and seven or eight soft rays. Species There are currently 12 recognized species in this genus: * ''Symphysanodon andersoni'' Adolf Kotthaus, Kotthaus, 1974 (Buck-toothed slopefish)Anderson, W.D.Jr., Chesalin, M.V., ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percoidea
Percoidea is a superfamily of fish of the order Perciformes. The superfamily includes about 3,374 species. Classification The Percoidesa are classified in the 5th Edition of the ''Fishes of the World'' as follows: * Percoidea ** Centropomidae (Snooks) ** Latidae (Lates) ** Gerreidae (Mojarras) ** Centrogenyidae (False scorpionfishes) ** Perciliidae (Southern basses) ** Howellidae (Oceanic basslets) ** Acropomatidae (Lanternbellies) ** Epigonidae (Deepwater cardinalfishes) ** Polyprionidae (Wreckfishes) ** Lateolabracidae (Asian seaperches) ** Mullidae (Goatfishes) ** Glaucosomatidae (Pearl perches) ** Pempheridae (Sweepers) ** Oplegnathidae (Knifejaws) ** Kuhliidae (Flagtails) ** Leptobramidae (Beachsalmon) ** Bathyclupeidae (Bathyclupeids) ** Polynemidae (Threadfins) ** Toxotidae (Archerfishes) ** Arripidae (Australasian salmon (kahawai)) ** Dichistiidae (Galjoen fishes) ** Kyphosidae (Sea chubs) ** Terapontidae (grunters or tigerperches) ** Percichthyidae ...

Taxa Named By Adolf Kotthaus
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
