Cyclopteridae
The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The family name ''Cyclopteridae'' derives from the Greek words ''κύκλος'' (kyklos), meaning "circle", and ''πτέρυξ'' (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish in this family. Description Lumpsuckers are named appropriately enough; their portly bodies are nearly spherical with generally drab coloration and lithic patterns. The "sucker" part refers to the fish's modified pelvic fins, which have evolved into adhesive discs (located ventrally, behind the pectoral fins); the fish use these discs to adhere to the substrate. Many species have bony, wart-like ''tubercles'' adorning the head and body; these are important taxonomic features of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eumicrotremus
''Eumicrotremus'' is a genus of lumpfishes native to the northern oceans. The name for this genus comes from the Greek roots ''eu'' meaning "good", ''mikros'' meaning "small" or "little", and ''trema'' meaning "hole". Species There are currently 16 recognized species in this genus (three additional species have been moved to ''Georgimarinus'', ''Microancathus'', and ''Proeumicrotremus'' and a species from ''Lethotremus'' has since been moved to this genus): * '' Eumicrotremus andriashevi'' Perminov, 1936 ** '' E. a. aculeatus'' Voskoboinikova & Nazarkin, 2015 (Andriashev's spicular-spiny pimpled lumpsucker) Voskoboinikova, O.S. & Nazarkin, M.V.

Proeumicrotremus
''Proeumicrotremus soldatovi'', also known as Soldatov's lumpsucker, is a species of lumpfish native to the Northwest Pacific, and the only species in the genus ''Proeumicrotremus''. It is known from the Sea of Okhotsk, where it can be found at depths of 10 to 350 m (33 to 1148 ft). It reaches 26 cm (10.2 inches) in total length, making it larger than average for a lumpfish. It was previously considered a species of ''Eumicrotremus'' until a morphology-based revision in 2020 concluded that it represents the only known species of a distinct genus. As of January 1, 2022, FishBase erroneously places the genus ''Proeumicrotremus'' in the family Cyclopsettidae alongside several flatfish A flatfish is a member of the Ray-finned fish, ray-finned demersal fish order (biology), order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes.

Cyclopterus Lumpus
''Cyclopterus lumpus'', the lumpsucker or lumpfish, is a species of marine fish in the family Cyclopteridae (lumpsuckers). It is the only member of the genus ''Cyclopterus''. It is found in the North Atlantic and adjacent parts of the Arctic Ocean, ranging as far south as Chesapeake Bay (rare south of New Jersey) on the North American coast and Spain (rare south of the English Channel) on the European coast.

Males typically reach in length while females can typically grow up to in length and in weight.Muus, B., J. G. Nielsen, P. Dahlstrom and B. Nystrom (1999). ''Sea Fish.'' pp. 180–181.

Scorpaeniformes
The Scorpaeniformes 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: 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 the midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral and caudal fins. Most species are less than in length, but the full size range of the order varies from the velvetfishes belonging to the family Aploactin ...

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation. In agriculture and horticulture * Cellulose substrate * Expanded clay aggregate (LECA) * Rock wool * Potting soil * Soil In animal biotechnology Requirements for animal cell and tissue culture Requirements for animal cell and tissue culture are the same as described for plant cell, tissue and organ culture (In Vitro Culture Techniques: The Biotechnological Principles).
