Cottunculus Sadko
''Cottunculus sadko'' is a species of marine ray-finned fish belonging to the family Psychrolutidae, the fatheads. This species is found from Greenland to the Norwegian and Kara Seas in the northeast Atlantic Ocean. However, some authorities regard this taxon as a synonym of the Polar sculpin ('' C. microps''). References {{Taxonbar, from=Q2590480 sadko Sadko () is a principal character in Russian '' byliny'' (oral epic poems). He is an adventurer, merchant, and '' gusli'' musician from Novgorod.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Psychrolutidae
The fish family Psychrolutidae (commonly known as blobfishes, flathead sculpins, or tadpole sculpins) contains over 35 recognized species in 8 genera. This family consists of bottom-dwelling marine sculpins shaped like tadpoles, with large heads and bodies that taper back into small, flat tails. The skin is loosely attached and movable, and the layer underneath it is gelatinous. The eyes are placed high on the head, focused forward closer to the tip of the snout. Members of the family generally have large, leaf-like pectoral fins and lack scales, although some species are covered with soft spines. This is important to the species as the depths in which they live are highly pressurized and they are ambush/opportunistic/foraging predators that do not expend energy unless they are forced to. The blobfish has a short, broad tongue and conical teeth that are slightly recurved and are arranged in bands in irregular rows along the premaxillaries; canines are completely absent. Teeth are ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottunculus Microps
''Cottunculus microps'', the polar sculpin, is a species of fathead sculpin, a deepwater fish found in the North Atlantic and Arctic Oceans. It was first described in 1875 by the Norwegian zoologist Robert Collett, curator of the Natural History Museum at the University of Oslo. Description Like other members of its family, the polar sculpin has a large head, a short tapering body and a small tail. The skin is loosely attached and there is a gelatinous layer beneath it. This fish has a maximum length of about but a more usual length is between . The head is rounded when viewed from above; its width is usually greater than its length. There are four rounded bony knobs behind and between the eyes and the skin is very rough. The colour of this fish is greyish-brown and there are three or four broad, dark-coloured vertical bands on the sides of the body. The dorsal fin has about 7 spines and 14 soft rays and the anal fin 10 to 11 soft rays. The pectoral fins are pale-coloured with ...
