Fissurella is a genus of small to medium-sized sea snails or limpets, marine gastropod mollusks in the family Fissurellidae, the keyhole limpets. [2]


The size of the body does not exceed or marginally exceeds that of the shell. The outer radular plate has four cusps. The propodium (= the anterior end of the foot) has no tentacles.


Like all other fissurellids, Fissurella species are herbivores, using the radula to scrape up algae from the surface of rocks.

Water for respiration and excretion is drawn in under the edge of the shell and exits through the "keyhole" at the apex.


According to the World Register of Marine Species (WoRMS), the following species with accepted names are included within the genus Fissurella [3]

Fissurella crassa
Fissurella latimarginata
Fissurella maxima
Fissurella radiosa tixierae, apical view
Fissurella rubropicta
Fissurella virescens
