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);  hispidus: Latin for bristly, referring to its skin being covered with minute stony tricuspid spines. (See ETYFish).
