Plicopurpura is the name of a genus of medium-sized snails in the spiny snail family, which includes three recognized species in the Eastern Pacific and the Caribbean .
features
The medium-sized to large, bulbous egg-shaped cases of the Plicopurpura species have a small, somewhat raised thread and a crooked, egg-shaped, very large body circumference that has no varices, but only smooth and knotty spiral hoops. The large and wide, egg-shaped housing mouth, which is broadly rounded at the top, is cut out at the bottom and ends in a very short channel. Your outer lip is covered with teeth on the inside or folded over in several places. The somewhat concave, flattened, calloused spindle has a wide, pressed edge and 1 to 2 spiral folds in the middle.
The snails are separate sexes with internal fertilization. Each mated female lays up to 150 bottle-shaped egg capsules, each containing around a hundred to a thousand eggs. These develop lecithotrophically in the capsules without nutritional eggs to form Veliger larvae, which hatch after a few weeks and go through a pelagic phase lasting several months , during which they feed on plankton. Finally, the metamorphosis into a snail takes place on the ground .
Occurrence and way of life
The snails of the genus Plicopurpura live in the Pacific Ocean on the coast of Central America and the Caribbean . The snails are mostly found on rocky ground in the intertidal zone. In particular, they feed on other snails, which they attack by pressing their proboscis under the operculum .
species
According to the World Register of Marine Species, the following three species belong to the genus Plicopurpura :
- Plicopurpura columellaris ( Lamarck , 1816) in the Eastern Pacific
- Plicopurpura eudeli (GB Sowerby III, 1903) in the Eastern Pacific
- Plicopurpura patula ( Linnaeus , 1758) in the Caribbean and the Eastern Pacific
Plicopurpura pansa (Gould, 1853) is henceforth a synonym for Plicopurpura columellaris .
