Low Tide Life: Atlantic Plate Limpet

Along the New England coastline, the only limpet who spends time in the intertidal zone is the Atlantic Plate Limpet (Testudinalia testudinalis). Also known as Tortoiseshell Limpets, these marine snails are typically no more than an inch long, so spotting them requires up close exploration.

I've occasionally encountered them while winkling at low tide in and around rocky tide pools. These snails prey on red algae; Atlantic Dogwinkles are among their predators.
