| Tegula funebralis (A. Adams, 1855) |
The Black Turban Snail, Tegula funebralis, is a gastropod (snail) that is found along the Pacific coast of North America from Vancouver Island to the Baja California peninsula.
Most have shells 20-40 mm in diameter.
They fare the best in rocky intertidal zones, where they graze on algae, microscopic films and wrack.
T. funebralis are sexually dimorphic, not hermaphroditic. They may live to the ages of twenty or thirty.
Predators of T. funebralis includes sea otters and predatory sea stars such as Pisaster ochraceous. When fleeing a predator on a sloped substrate, they may simply detach and roll away.
Their shells are often used by hermit crabs and appear to be a favorite.
