Acochlidacea

The Acochlidacea are a small order of marine and freshwater gastropods, characterized by their reduced or absent shells and often elongated visceral mass. They are found in various aquatic environments, from shallow waters to deeper sediments.1

Gastropods, as a class, exhibit remarkable diversity in their habitats, feeding habits, and reproductive systems. Their feeding mechanisms often involve a radula, a ribbon-like structure with teeth used for scraping food. While many gastropods are herbivores, some are carnivorous, predatory, or parasitic. Reproduction varies, with some species having separate sexes and others being hermaphroditic. The classification of gastropods has undergone significant revisions, with ongoing research utilizing both traditional anatomical studies and molecular data.2341
