Taxonomy and distribution of the Neritidae (Mollusca: Gastropoda) in Singapore

Taxonomy and distribution of the Nerifidae (Mollusca: Gastropoda) in Singapore. Zoological Studies 47(4): 481-494. Molluscs from the gastropod family Neriticlae are primarily found in marine habitats, but they are also known from brackish and freshwater systems. In Singapore, there is a paucity of information on the diversity of Neritids in all 3 aquatic environments. Herein, we provide taxonomic descriptions and distributional data for locally occurring Neritids. Surveys of 31 sites over a period of 10 yr yielded a total of 19 species, of which 6 species are considered new records for Singapore.
