Freshwater neritids (Mollusca: Gastropoda) of tropical islands, amphidromy as a life cycle, a review

Abstract : Tropical island freshwaters are inhabited by Molluscs of the Neritidae family with a specific life cycle adapted to the insular environment. The adults grow, feed and reproduce in rivers. After hatching the larvae drift downstream towards the sea where they spend a variable amount of time. This life cycle is called amphidromous. Although this is the most diverse family of freshwater Molluscs, the biological cycle and the parameters and evolutionary processes that lead to such diversity are not well understood. This paper reports on the current knowledge on reproduction, recruitment, upstream migration and dispersal. Management and restoration strategies to preserve amphidromous Neritids require the development of research to get a better understanding of their life cycle.
