Where to find
Intertidal rocky reefs
The edge of the shell of this limpet is wavy, making it easy to distinguish from the Variegated Limpets with which they share the intertidal zone. Shell to 6 cm wide and 4 cm high

Like all limpets, this species uses a chainsaw-like tongue to scrape microalgae off the surface of rocks.
