Élasmobranches (requins et raies) (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); stewarti: In honor of the late Rob Stewart (1979-2017), Canadian filmmaker and shark conservationist, who “inspired the second author and stimulated her interest in sharks” (he died from hypoxia while diving off Islamorada, Florida, USA). (See ETYFish).
