Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0. Numerous dark spots on lower lobe of caudal fin (Ref. 31369). Pectoral fins greatly enlarged, with broad triangular lobe extending forward from their bases on either side of the gill slits; pelvic fins enlarged and wing-like; caudal very short, nearly symmetrical but not lunate, its lower lobe slightly longer than the upper (Ref. 31369).
Body shape (shape guide): other.
A common but little-known angelshark found on the continental shelf and uppermost slope, on or near the bottom (Ref. 247, 75154). Occurs from close inshore to 130 m depth (Ref. 31369, 6871). Feeds mainly on small fishes and crustaceans (Ref. 6871). Ovoviviparous (Ref. 247). Flesh is highly esteemed (Ref. 6871).
