Các tia vây lưng cứng (tổng cộng) : 0; Tia cứng vây hậu môn: 0. Bright yellow or golden spots on a dark grey body with irregular blotches and saddles (Ref. 5578), cream below (Ref. 5510); 2nd dorsal much smaller than 1st (Ref. 5578). Small anterior nasal flaps that do not reach mouth, no nasoral grooves (Ref. 244).
A common inshore to offshore catshark. Prefers to feed on small bony fishes and crustaceans, also cephalopods (Ref. 244). Oviparous (Ref. 50449).
Oviparous, with a single egg per oviduct at a time (Ref. 244). Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Size upon hatching below 31 cm (size of young with umbilical scars) (Ref. 244).
