Tortoiseshell Limpet, Acmaea testudinalis (6)

Limpets are mollusks which have only one shell. Most often seen in the intertidal zone, they graze on algae on the rocks when underwater, and cling tightly to the rock when the tide goes out. Seen near Petit-Vallee, Quebec. The shell is 18 mm long.

There are a few small Periwinkles, Littorina littorea, surrounding the limpet.
