Volcano Keyhole Limpet

provided by EOL authors
Fissurella volcano, is a marine gastropod, in the Phylum Mollusca, that survive on the undersurface of rocks (Roy et al 2003).There are many color possibilities for this species:browns, pinks, purples and grays(Tway 2011). It is characterized as a small limpet because its size ranges from 1.27 to 2.54 centimeters(Tway 2011).The northeastern Pacific, volcano limpet, appeared in southern California during the early Pleistocene,"but after its first occurrence it is a common and abundant species in most subsequent Pleistocene faunas "(Lindberg 1991). When fleeing predators, such as thePisaster ochraceus, the keyhole limpet displays a fleeing response to retreat from the approaching predator (Bullock 1953).

Fissurella volcano

provided by wikipedia EN

Fissurella volcano, commonly named the volcano limpet or volcano keyhole limpet, is a species of small to medium-sized sea snails, marine gastropod mollusks in the family Fissurellidae, the keyhole limpets. Like other members of the keyhole limpet family, the volcano limpet is not considered a "true" limpet.

Adults measure up to approximately 2.5-4.1 cm with a keyhole-shaped pore on the apex of its conical shell. They feed on benthic microalgae and potentially some macroalgal, or seaweed, fronds.

This species occurs in the Western Pacific Ocean, where it is found in the intertidal zone on the underside of rocks. The distribution is California and Baja California.
