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).
在尾鳍的低叶上的很多的深色斑点.(参考文献 31369) 胸鳍明显增大, 有宽的在鳃缝的任一侧边上从他们的基底向前延伸的三角形的叶; 腹鳍增大了与翼状的; 尾部的非常短的, 几乎对称但是不是新月状, 它的下叶略长于上面者.(参考文献 31369)
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).
