Every dive site off this coast has a few, tucked under a ledge in a row, going nowhere in particular. They have a flat head, a slim body and unmistakable white tips to the dorsal and tail fins, and they regard divers with complete indifference.
Where you’ll see it
The Catalina Islands, the Papagayo headlands and the rocky reefs along the coast, resting in caves and under overhangs during the day. At night they hunt octopus and small fish in the rocks.
What to know
A small shark with a small mouth and a timid nature. It can rest on the bottom because it pumps water over its gills rather than needing to swim. Divers see them on most trips and the only rule is not to poke, corner or grab one, which no reasonable person would.
