Description

The tawny nurse shark is a large nurse shark (Ginglymostomatidae) from the Indo-Pacific. The species grows to about 3.2 metres and has a robust, tawny-brown body with a broad, blunt head, small eyes and a pair of barbels. As a nocturnal bottom-dweller it rests by day in caves and under overhangs and at night sucks prey from crevices with powerful suction jaws: crustaceans, octopus and fish. It is usually placid, but can bite fiercely and clamp hard when disturbed; caution is advised.
