This limpet has detected the adjacent giant seastar chemically and is raising its protective mantle. Thus the predatory seastar's tube feet will be unable to adhere to the limpet. The limpet's excurrent keyhole is present on the dorsum. Depth 15 m. Subclass prosobranchia.
We are fortunate that the little goby posed for us on this keyhole limpet. These limpets include seaweeds and colonial tunicates in their diet. Coastal Indians used the shells of these and other limpets as wampum. Subclass Prosobranchia.
