Life habits
Like all other fissurellids, ''Diodora'' species are herbivores, and use the
radula
The radula (; : radulae or radulas) is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters ...
to scrape algae from rocks. An exception is ''D. apertura'', which grazes on sponges such as ''
Hymeniacidon''.
Water for respiration and excretion is drawn in under the edge of the shell and exits through the "keyhole" at or near the apex.
