Location of Costa Rica

The non-marine molluscs of Costa Rica are a part of the wildlife of Costa Rica. 233 species and subspecies have been reported (50 freshwater and 183 terrestrial), however scientists estimate that a full inventory can reach up to 300 or 400 species.[1]

The terrestrial gastropods reported for Costa Rica belong to 25 families and 59 genera, and include 11 doubtful identifications.[2] Species are commonly found in paramo and oak forests[3] Samples of the species collected in Costa Rica can be found in the Museum of Zoology of the Universidad de Costa Rica.[4][5]

The terrestrial malacofauna of Costa Rica presents an endemism of 31% in terrestrial species and 8% in freshwater species. These species can be affected by water pollution, deforestation and the destruction of calcium-rich habitats.[1]
