Lewis moon snail
Latin Name:	Polinices lewisii
Geographic Range:	Range is from Vancouver Island to Baja.
SCUBA Divers Info:
Its hard to miss this snail since it can reach almost a foot in length. It is so big in fact that it's shell is hardly visible under the mass of mantle. It lays circular egg cases called sand collars made of sand stuck together with mucus to protect its eggs. These snails eat clams, they drill into the clam at the hinge end using their radula leaving a characteristic counter-sunk hole.
Beachwalkers Info:
Look carefully at low tide in sand bays and eel grass beds for the partially buried moon snail or its "sand collar" egg cases.
