Very similar to Chitons, as they also have a conical half-shell appearance, except this species has a small opening in the center top portion of its shell. Basically herbivores and small in size, i.e., about an inch or much less (5 mm - 2.5 cm). Often arrive on live rock and can be quite useful in controlling microalgae and diatom blooms.
