Etymology: Halaelurus:halos (Gr.), sea; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish); maculosus:Latin for speckled, referring to speckling of small dark spots over dorsal and lateral surfaces of body. (See ETYFish). More on authors: White, Last & Stevens.
