Marisa cornuarietis (Linnaeus, 1758) (Gastropoda: Ampullariidae): a new addition to the freshwater malacofauna of Jamaica with health and economic implications.

Abstract

Marisa cornuarietis (Linnaeus, 1758) (giant ramshorn snail) is an aquatic snail of the family Ampullariidae Gray, 1824, which are generally referred to as apple snails. Several ampullariids, including M. cornuarietis, are invasive alien species across several islands of the Caribbean, where they are associated with considerable ecological and economic outcomes. During an aquatic snail assessment survey conducted from May to June 2021, 153 giant ramshorn snails were collected from two ponds and trenches exiting those ponds in the parish of St. Andrew, Jamaica. The specimens were photographed and carefully identified using distinguishing morphological features. Here we confirm the presence of the species in Jamaica and discuss potential environmental, economic, and social implications of this invasive species.
