Shape characteristics of Baoluo nut
Cypraea cinerea (scientific name: Cypraea cinerea) is a mollusk of Gastropoda. The shell is oval, and the spiral layer is involute. The shell is long and narrow, with fine teeth on the outer and inner lips. The mantle is thin and bilobate, and the shell is almost completely covered in the living body. The helix almost disappeared from the adult, but the adult did not. The shell surface is smooth and glossy, and the patterns are colorful. It lives in tropical and subtropical warm sea areas, and can be traced from intertidal zone to deep reef, coral reef or sediment seabed. It mainly feeds on algae or corals. Because of its beautiful shape, it is favored by the majority of shellfish collectors and has high ornamental and collection value.
Distributed in North Carolina, from the United States to Colombia to the east of Brazil.
Living in the tropical and sub zone shallow sea, it often lives in the reef bottom near the low tide line of the intertidal zone. When the tide recedes, many people hide under the rocks of the reefs, between the gaps and caves of the coral reefs. They move slowly and are afraid of strong light. They hibernate in coral caves or rocks during the day and go out to look for food at dawn or dusk. They are carnivorous species. They prey on sponges, foraminifera, algae, corals and small crustaceans with their tongues.
It is hermaphroditic. The spawning season is from March to July. The eggs are usually laid in coral caves, empty shells and dark places. After laying eggs, the female does not leave the egg group, but lies on the top of the egg group to protect it deliberately until hatching.
