Diodora is a genus of small to medium-sized keyhole limpet in the family Fissurellidae.

Life habits

Like all other fissurellids, Diodora species are herbivores, and use the radula to scrape algae from rocks. An exception is D. apertura, which grazes on sponges^[1][2] such as Hymeniacidon.^[3]

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