Description

The draughtsboard shark is a swellshark (Scyliorhinidae) from coastal waters around New Zealand. The species grows to about 1 metre and has a stocky, yellow-brown body with a draughtsboard pattern of dark saddle marks and spots. When threatened it can swell up with water (or air) to wedge itself in a crevice or look larger. As a nocturnal bottom-dweller it hunts crustaceans, molluscs and small fish and lays eggs in horny capsules. This sluggish shark is harmless to humans.
