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); giddingsi: In honor of Al Giddings (b. 1937), American underwater filmmaker, naturalist, and friend (See ETYFish).
Eponymy: Al Giddings is an underwater filmmaker and naturalist. He has also been active in the commercial film business as the cameraman for: The Deep (1977) and as co-producer of: Titanic (1997). Moreover, he is a friend of the senior author. (Ref. 128868), visit book page.
