Bithynia cretensis

Unknown

Overview

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

Bithynia cretensis is a freshwater snail restricted to a small number of springs and streams on Crete, making it highly vulnerable to localized hydrological disturbance. Water abstraction for agriculture and tourism development has reduced flow and altered the freshwater habitats this species depends on for survival. Pollution from agricultural runoff and the modification of spring outlets for water collection further degrade the limited habitat available to this narrow-range endemic.
