Antarctic Dragonfish
The Bathydraconidae, or the Antarctic dragonfishes, are a family of marine ray-finned fishes, notothenioids belonging to the Perciform suborder Notothenioidei. The family comprises four genera. These fishes are endemic to deep waters off Antarctica. Taxonomy Bathydraconidae was first formally described as a family in 1913 by the English ichthyologist Charles Tate Regan in his report on the fishes collected on the Scottish National Antarctic Expedition to the Royal Society of Edinburgh. He used the genus ''Bathydraco'', which had been described by Albert Gunther in 1878 as a monotypic genus with '' B. antarctica'' as its type species, as the type genus. Molecular analyses have supported the split of bathydraconids into three clades; Bathydraconinae which includes ''Bathydraco'', '' Prionodraco'' and ''Racovitzia''; Gymnodraconinae which includes '' Gymnodraco'', ''Psilodraco'' and ''Acanthodraco''); and Cygnodraconinae including '' Cygnodraco'', '' Gerlachea'' and ''Parachaenichth ...

Bathydraco Antarcticus
''Bathydraco'' is a genus of marine ray-finned fishes belonging to the family Bathydraconidae, the Antarctic dragonfishes. They are native to the Southern Ocean. Taxonomy ''Bathydraco'' was first described as a genus in 1878 by the German-born British ichthyologist Albert Günther as a monotypic genus with '' B. antarctica'', which had been collected on the Callenger expedition south of Heard Island, as its type species.

Species There are currently five recognized species in this genus: * '' Bathydraco antarcticus'' Günther, 1878 * '' Bathydraco joannae'' H. H.

Fishes Of The World
''Fishes of the World'' by the American ichthyologist Joseph S. Nelson (1937–2011) is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family (biology), family gets at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, while the book generally does not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not involve color illustrations. The fourth edition was the first to incorporate the wide use of DNA analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
