Blue-eyed Aquatic Treefrog

Sarcohyla cyanomma

Declining

Overview

Sarcohyla cyanomma, also known as the blue-eyed aquatic treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico and only known from the northern slope of Cerro Pelón, in Sierra de Juárez in northern Oaxaca. It is feared that the species might be extinct.

Sarcohyla cyanomma faces severe population decline due to habitat destruction from agricultural expansion and urban development in its limited montane range. The species is particularly vulnerable to chytrid fungal infections, which have devastated amphibian populations throughout Central America. Climate change poses an additional threat by altering the cool, humid conditions essential for this cloud forest specialist.

Threat summary

Habitat

This species inhabits montane cloud forests and pine-oak forests at elevations between 1,200-2,400 meters in the Sierra Madre Oriental of Mexico. It requires cool, humid microhabitats with persistent moisture and dense vegetation cover typical of these high-elevation ecosystems.

Frequently asked questions

Why is Blue-eyed Aquatic Treefrog classified as Critically Endangered?
Blue-eyed Aquatic Treefrog 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. Sarcohyla cyanomma faces severe population decline due to habitat destruction from agricultural expansion and urban development in its limited montane range. The species is particularly vulnerable to chytrid fungal infections, which have devastated amphibian populations throughout Central America. Climate change poses an additional threat by altering the cool, humid conditions essential for this cloud forest specialist.
Where does Blue-eyed Aquatic Treefrog live?
Blue-eyed Aquatic Treefrog occurs in Mexico. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Blue-eyed Aquatic Treefrog?
The main threats to Blue-eyed Aquatic Treefrog are 5.2, 5.4, 8.1, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
