Cerion nana

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Cerion nana faces severe threats from habitat destruction due to coastal development and tourism infrastructure expansion across its limited range in the Bahamas. The species' extremely restricted distribution makes it particularly vulnerable to hurricanes and storm surge events, which can devastate entire populations. Invasive plant species are altering the native vegetation communities that this land snail depends upon for shelter and food sources.
