Description

The hidden angelshark is an angelshark (Squatinidae) from coastal waters of the southwest Atlantic off Brazil, Uruguay and Argentina. The species grows to about 1.3 metres and has a strongly flattened body with broad, wing-like pectoral fins, so it resembles a ray, but with the mouth at the front as in a shark. As a motionless ambush hunter it lies buried in sand and snaps lightning-fast at passing fish and squid. When handled or stepped on it can bite fiercely; through fishing it is strongly endangered.
