Lebiasina marilynae

Unknown

Overview

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

Lebiasina marilynae faces primary threats from habitat degradation due to agricultural expansion and cattle ranching in its limited range within the Orinoco River basin. Water quality deterioration from agricultural runoff and sedimentation poses significant risks to this freshwater species. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human activities affecting stream ecosystems.
