Allotoca maculata

Declining

Overview

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

Allotoca maculata faces severe population decline primarily due to habitat degradation and water pollution in its native Mexican freshwater systems. The species has experienced dramatic range reduction, with several historical populations now extinct due to urban development and agricultural runoff contaminating its spring-fed habitats. Introduction of non-native fish species has further compromised remaining populations through predation and competition.
