'''''Diodora''''' is a genus of small to medium-sized keyhole limpet in the family Fissurellidae.<ref name="WoRMS">Bouchet, P.; Gofas, S.; Rosenberg, G. (2012). Diodora J. E. Gray, 1821.

== 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<ref>{{Cite journal | journal=Journal of Molluscan Studies|title=Torsion and the adult snail: a re-evaluation|date=1958|volume=33|issue=1|pages=2–10|doi=10.1093/oxfordjournals.mollus.a064794 |last1=Morton|first1=J.

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