Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A large catshark with short nasal barbels and long horizontal black stripes (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Occurs in the continental shelf, both inshore and offshore (Ref. 5578). Prefers rocky reefs from the intertidal zone down to 100 m depth (Ref. 5578). Nocturnal, often found in caves and crevices during the day (Ref. 5578). Feeds mainly on crustaceans, but also bony fish and cephalopods (Ref. 244). Oviparous (Ref. 50449). Readily kept in captivity (Ref. 244).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, with a single egg-case per oviduct (Ref. 244). Embryos feed solely on yolk (Ref. 50449). Size at hatching between 14 and 15 cm.
