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.

preoral length 4.7-6.8% TL; short head, length about equal to pectoral-pelvic space, 21-24% TL; precaudal length 73-80% TL; dorsal and anal fins are subequal; length of anal-fin base about equal to length of interdorsal space; 81-85 (mean = 82.6) precaudal vertebrae; color chocolate brown dorsally, paler on ventral surface from snout to anus; body, flanks, caudal and median fins are overlain with pale spots about equal in size to eye, becoming smaller below lateral midline, and showing a bilaterally asymmetrical pattern. It differs from its congeners in its coloration, the length of its anal-fin base, and in other morphological characters (Ref. 89625).
