Dolomiidina

Dolomiidina is a genus of small, marine gastropod mollusks belonging to the family Fissurellidae, commonly known as keyhole limpets. These limpets are characterized by a distinctive hole or slit at the apex of their shell. The shell itself is generally conical, with a sculpture that can vary but often includes radial ribs. The size of dolomiidina species is typically small, with shells usually measuring only a few millimeters in length.

The distribution of dolomiidina is primarily found in the Indo-Pacific region, inhabiting a range of subtidal environments. They are often found attached to hard substrates such as rocks and coral. As with other limpets, dolomiidina are herbivores, feeding on algae scraped from surfaces. Their morphology, particularly the shell shape and the apical opening, plays a role in their respiration and waste expulsion.

While the genus dolomiidina is recognized, specific species within it may be subject to ongoing taxonomic research and revision. Due to their small size, they are not commonly encountered by casual observers and are more often a subject of interest for marine biologists and malacologists. The ecological role of dolomiidina, like other grazing gastropods, contributes to the health of reef ecosystems by controlling algal growth.
