Overview

Anomaloglossus degranvillei is a species of frog in the family Aromobatidae. It is known from French Guiana but is likely to occur also in Suriname and Brazil, and possibly in Guyana. It is named in honour of Jean-Jacques de Granville, a botanist from French Guiana.

Anomaloglossus degranvillei faces severe threats from gold mining activities that destroy its pristine forest habitat through hydraulic mining, mercury contamination, and sedimentation of streams. The species' extremely restricted range in French Guiana makes it particularly vulnerable to habitat fragmentation from expanding mining concessions. Climate change poses additional risks through altered precipitation patterns that could disrupt the delicate moisture conditions required for breeding in leaf litter and small forest pools.

Threat summary

Habitat

This critically endangered poison frog inhabits pristine primary rainforest in the Guiana Shield region of French Guiana, specifically in areas with dense leaf litter and small temporary pools. The species requires undisturbed forest with high humidity levels and is typically found in association with granite outcrops and seasonal water bodies essential for reproduction.
