Pseudobithynia euboeensis

UnknownCREUCREU

Overview

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

Pseudobithynia euboeensis faces severe threats from habitat degradation and water pollution in its limited freshwater spring systems on Euboea Island, Greece. The species' extremely restricted range makes it highly vulnerable to local environmental changes, including agricultural runoff, urban development, and alterations to natural spring hydrology. Climate change poses an additional threat through potential changes in groundwater levels and spring flow patterns that could eliminate the specialized aquatic microhabitats this endemic gastropod requires.

Threat summary

Habitat

This critically endangered freshwater snail is endemic to natural spring systems and associated freshwater habitats on the Greek island of Euboea. It inhabits clean, calcium-rich spring waters with specific temperature and flow characteristics typical of Mediterranean karst spring environments.
