Description

The leopard shark is a handsomely marked houndshark of the family Triakidae from the eastern Pacific. The species grows to about two metres and has a slender, grey body with conspicuous dark saddle blotches and spots, like a leopard. It lives in shallow water from the intertidal to deeper waters, most commonly in sheltered bays, estuaries and kelp forests, often in large schools. As a bottom hunter it feeds on crabs, shrimps, worms, shellfish and small fishes. The leopard shark is not dangerous to humans and is often seen by divers, but it remains a shark with sharp teeth; handle a caught specimen with care.
