A robust catshark with a broadly rounded snout; skin rough with widely-spaced denticles; labial furrows absent. Brownish to greyish a darker blotched or mottled pattern and a broad dark saddle on the back between the eye and the pectoral in base; belly with a dark median stripe. Length to 1.5 m, most below 1 m.
When caught, this slow-moving species "puffs" up its body by inflating its stomach with air or water. Females lay yellowish egg cases with distinct transverse ridges and long spirally tendrils that attach to seaweed or sessile invertebrates in the bottom. The young sharks hatch after about 12 months.
On sandy bottoms and rocky reefs in bays, harbours and along the coast, to depths of about 60 m.
Although considered harmless to humans, has the potential to bite.
