Description

The Mexican hornshark is a bullhead shark (Heterodontidae) from the eastern Pacific. The species has a stocky body with a blunt, pig-like head, conspicuous brow ridges and, in front of each of the two dorsal fins, a stout spine. It inhabits rocky and sandy coastal bottoms from close inshore to at least 20 m deep. As a slow bottom hunter it cracks hard-shelled prey such as molluscs, crustaceans and sea urchins with its flattened rear teeth. It reproduces with spiral egg cases. The dorsal fin spines can give a painful puncture wound when handled; otherwise it is harmless.
