''Lethotremus'' is a genus of lumpfishes native to the northern Pacific Ocean. Following a 2017 taxonomic review by Lee et al., the species ''Lethotremus awae'' was reclassified as a species of ''Eumicrotremus ''Eumicrotremus'' is a genus of lumpfishes native to the northern oceans.

Lethotremus Muticus
''Lethotremus muticus'', also known as the docked snailfish (a somewhat misleading name as this species is not one of the true snailfish in the family Liparidae), is a species of lumpfish native to the Northeast Pacific. It is known from the Bering Sea and the Aleutian Islands, where its range extends to Unimak Pass, and it occurs at a depth range of 58 to 330 m (190 to 1082 ft). It is a benthic species that reaches 11.5 cm (4.5 inches) in total length. It can be found on substrates of mud, rock, or gravel, and it is currently the only known species of ''Lethotremus'', following a reclassification of the second described species in the genus as ''Eumicrotremus awae ''Eumicrotremus awae'' is a species of lumpfish endemic to the Pacific coast of Honshu, Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia.

Lumpfish
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.

Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservation movement, conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 187 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Pacific Ocean
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 continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
