Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) 棘鮫目 (Sleeper and dogfish sharks) > Dalatiidae (Sleeper sharks) 黑鮫科 (Sleeper sharks)
Etymology: Dalatias:Etymology not explained nor evident. A few online sources suggest Dalatias is derived from dalos (Gr.), torch or firebrand, but nothing in Rafinesque’s description supports this interpretation. Interestingly, D. licha is bioluminescent, a fact that was discovered and resported only recently and was certainly unknown to Rafinesque and other early naturalists. See: Mallefet J., D. W. Stevens, and L. Duchatelet. 2021. Bioluminescence of the largest luminous vertebrate, the kitefin shark, Dalatias licha: first insights and comparative aspects. Frontiers in Marine Science 8 (article 633582): 1-13. (See ETYFish); licha:Latinization of “La Liche” as reported by Broussonet (1780), an old French word for this shark, possibly from from the Occitan lecha or lec, meaning “glutton”. (See ETYFish).
