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); lutarius: Latin for “of the mud,” referring to its habitat on or just above muddy bottoms at 338-766 m. (See ETYFish).
