Typhleotris mararybe

Stable

Overview

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

Typhleotris mararybe faces severe threats from groundwater extraction and pollution in its limited cave habitat range in Madagascar. The species' extremely restricted distribution makes it highly vulnerable to any disturbance of the underground aquifer systems it depends upon. Agricultural runoff and potential mining activities pose additional risks to water quality in the karst limestone regions where this blind cavefish occurs.

Threat summary
