Neverita lewisii lives in the Eastern Pacific, from British Columbia to northern Baja California, Mexico.
This snail is found intertidally and at depths of up to 180 metres (590 ft), usually ploughing through the substrate looking for prey.
It has an extremely large foot, which when the snail is active, is extended up over the shell and mantle cavity.
Part of the propodium contains a black-tipped siphon which leads water into the mantle cavity.
The eggs may number in the thousands and hatch into microscopic larvae which feed on plankton until they undergo torsion and metamorphose into the adult stage.
