板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) >
Carcharhiniformes (Ground sharks) >
Pentanchidae (Deepwater catsharks)
Etymology: Bythaelurus: bythos (Gr.), depths of the sea, referring to its deepwater habitat; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish); alcockii: In honor of physician-naturalist Alfred William Alcock (1859-1933), who noted the distinctiveness of this species in 1896. (See ETYFish).
