Euglesa maasseni

Unknown

Overview

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

Euglesa maasseni faces severe threats from habitat degradation and water quality deterioration in its limited freshwater environments. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes, with pollution from agricultural runoff and urban development posing immediate risks to its aquatic habitat. Climate-induced changes to water temperature and chemistry further compound these pressures on this critically endangered freshwater bivalve.

Threat summary

Habitat

Frequently asked questions

Why is Euglesa maasseni classified as Critically Endangered?
Euglesa maasseni is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Euglesa maasseni faces severe threats from habitat degradation and water quality deterioration in its limited freshwater environments. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes, with pollution from agricultural runoff and urban development posing immediate risks to its aquatic habitat. Climate-induced changes to water temperature and chemistry further compound these pressures on this critically endangered freshwater bivalve.
Where does Euglesa maasseni live?
Euglesa maasseni occurs in Albania, and North Macedonia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Euglesa maasseni?
The main threats to Euglesa maasseni are 11.1, 2.1, 8.1, and 9.3. The full IUCN-classified threat record for this species is detailed on the species page.
