The results showed that the types of molluscs found were molluscs in the gastropod group such as moon eye snail, oliva reticulata, hexaplex trunculus, lola and abalone. Molluscs are one of the macrozoobenthos groups that have soft bodies and mostly secrete calcium carbonate which forms a hard shell of chitin substance that functions in self-protection. (Candri et al., 2020)The ecosystem owned by this type of mollusk has decreased in number, because it is used as a food source by the surrounding community. In addition, Lakeba beach in Baubau City is also a tourist spot and is close to residential areas so as to reduce the amount of mollusk diversity. So this research is important to do.
