Hymenogadus Gracilis
''Hymenogadus gracilis'', also known as the Graceful grenadier is a species of rattail fish. It is found at depths of in tropical and subtropical seas worldwide. This is one of the smallest of the rattails, growing to no more than in length. It is a slender fish with a large mouth, with rows of very small teeth, positioned in the underside of the skull. There is a short, thin chin barbel. It is more strikingly marked than most rattails, with bold black streaks on the head and black and silver barring over most of the body. There is a long bioluminescent Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some Fungus, fungi, microorganisms including ... organ with two lenses underneath the rear end of the body.

Rattail
Grenadiers or rattails are generally large, brown to black gadiform marine fish of the subfamily Macrourinae, the largest subfamily of the family Macrouridae. Found at great depths from the Arctic to Antarctic, members of this subfamily are amongst the most abundant of the deep-sea fish. The macrourins form a large and diverse family with 28 extant genera recognized (well over half of the total species are contained in just three genera, ''Coelorinchus'', ''Coryphaenoides'', and ''Nezumia''). They range in length from about in ''Hymenogadus gracilis'' to in ''Albatrossia pectoralis''. Several attempts have been made to establish a commercial fishery for the most common larger species, such as the giant grenadier, but the fish is considered unpalatable, and attempts thus far have proven unsuccessful. The subfamily as a whole may represent up to 15% of the deep-sea fish population. Rattails, characterized by large heads with large mouths and eyes, have slender bodies that tap ...

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 ...

Carl Leavitt Hubbs
Carl Leavitt Hubbs (October 19, 1894 – June 30, 1979) was an American ichthyologist. Biography Youth He was born in Williams, Arizona. He was the son of Charles Leavitt and Elizabeth (née Goss) Hubbs. His father had a wide variety of jobs (farmer, iron mine owner, newspaper owner). The family moved several times before settling in San Diego where he got his first taste of natural history. After his parents divorced in 1907, he lived with his mother, who opened a private school in Redondo Beach, California. His maternal grandmother Jane Goble Goss, one of the first female doctors, showed Hubbs how to harvest shellfish and other sea creatures. One of his teachers, impressed by Hubbs's abilities in science, recommended that he study chemistry at the University of Berkeley. The family moved once more to Los Angeles. In Los Angeles, George Bliss Culver, one of the many volunteers of David Starr Jordan, encouraged Hubbs to abandon his study of birds and instead to study fish, par ...

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 ...
