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.
