Widemouth Rocksnail

Plicopurpura patula

Plicopurpura patula is a marine gastropod mollusk characterized by its robust shell, which can grow up to 8.5 cm in length. The shell is typically thick and has a wide mouth, distinguishing it from similar species. This species is found in the tropical Western Atlantic, with a distribution range extending from Florida to Trinidade, including the Caribbean Sea. It inhabits intertidal splash zones on hard rocky shorelines that experience regular wave action, and it can also be found in coral reefs and rocky habitats. The depth range for this species is generally from 0 to 2 meters, with occurrences reported at depths shallower than 40 meters, and most records being less than 10 meters deep. Widemouth Rocksnails are non-broadcast spawners, meaning they do not release their eggs into the water column. They do not undergo a trocophore stage in their life cycle, which is typical for many marine gastropods. These snails are primarily benthic, feeding on small invertebrates and possibly detritus. Encounters with this species during dives can be intriguing, as they often cling to rocky surfaces, blending in with their surroundings. Divers may observe them in their natural habitat, often in areas with significant wave action. The conservation status of Plicopurpura patula is currently not evaluated, and there are no specific threats noted. However, its presence in a wide range of dive sites suggests it may be relatively common within its preferred habitats.
