Diodora Explained

Diodora is a genus of small to medium-sized keyhole limpet in the family Fissurellidae.^[1]

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^[2] ^[3] such as Hymeniacidon.^[4]

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