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 ...

Pleuronectiformes
A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. Many important food fish are in this order, including the flounders, soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Over 800 described species are placed into 16 families. Broadly, the flatfishes are divided into two suborders, Psettodoidei and Pleuronectoidei, with > 99% of the species diversity found within the Pleuronectoidei. The largest families are Soleidae, Bothidae and Cynoglossidae with more than 150 species each. There also exist two monotypic families (Paralichthodidae and Oncopteridae). Some families are ...

Pleuronectidae
Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the opposite, with their eyes on the left side. A small number of species in Pleuronectidae can also have their eyes on the left side, notably the members of the genus ''Platichthys''. Their dorsal and anal fins are long and continuous, with the dorsal fin extending forward onto the head. Females lay eggs that float in mid-water until the larvae develop, and they sink to the bottom. They are found on the bottoms of oceans around the world, with some species, such as the Atlantic halibut, ''Hippoglossus hippoglossus'', being found down to . The smaller species eat sea-floor invertebrates such as polychaetes and crustaceans, but the larger righteye flounders, such as ''H. hippoglossus'', which grows up to in length, feed on other fishes and cep ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Kareius
The stone flounder (''Kareius bicoloratus'') is a flatfish of the family Pleuronectidae. It is a demersal fish that lives on sandy and muddy bottoms in coastal areas at depths of up to . Its native habitat is the temperate waters of the northwest Pacific, from Japan to the Kuril islands, Sakhalin, Korea, northern China and Taiwan. It is oceanodromous and is found in salt, brackish and fresh waters. It can grow up to in length, and may reach 12 years of age. Diet The stone flounder's diet consists of zoobenthos organisms such as amphipods, bivalves, mysids and polychaete Polychaeta () is a paraphyletic class (biology), class of generally marine invertebrate, marine annelid worms, common name, commonly called bristle worms or polychaetes ().

Limanda
''Limanda'' is a genus of righteye flounders native to the northern Atlantic and Pacific oceans. A 2018 cladistic morphological and genetic analysis found that the genus is not monophyletic, and has proposed ''L. ferruginea'', ''L. proboscidea'' and ''L. punctatissima'' be placed in the genus ''Myzopsetta''. Species There are currently six recognized species in this genus: * ''Limanda aspera'' (Pallas, 1814) (Yellowfin sole) * ''Limanda ferruginea'' ( D. H. Storer ( fr), 1839) (Yellowtail flounder) * ''Limanda limanda'' (Linnaeus, 1758) (Common dab) * ''Limanda proboscidea'' C. H.

Parophrys
The English sole (''Parophrys vetulus'') is a flatfish of the family Pleuronectidae. It is a demersal fish that lives on sandy and muddy bottoms in estuaries and near shore areas, at depths of up to . It reaches up to in length, and can weigh up to . Its native habitat is the Pacific Ocean, Eastern Pacific, stretching from the coast of Baja California in the south to the Bering Sea in the north. English sole is an important commercial fish, primarily caught off Washington (U.S. state), Washington, Oregon and California. Though Biomass (ecology), biomass is increasing, catches have been declining since the 1960s and are currently almost at an all-time low. The English sole is known in Spanish as ''platija limón'', or lemon sole, a name by which it is also known in English, though the true lemon sole is a separate species, ''Microstomus kitt''. Etymology The genus name is derived from the Greek ''para'', meaning "near", ''ophrys'', meaning "eyebrow", and the species name ''vetu ...

''Platichthys'' is a genus of flatfish native to the North Pacific The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continen ... and North Atlantic oceans. Despite being in the family Pleuronectidae (popularly known as righteye flounders), all three species in the genus ''Platichthys'' are often "lefteyed", i.e. they lie on the sea bottom on their right side, with both eyes on the left side.
