Rucilla Streamside Frog

Eleutherodactylus rucillensis

Declining

Overview

Eleutherodactylus rucillensis is a little-known species of frog within the family Eleutherodactylidae. It is thought to occur in parts of the Caribbean, though its exact range has not been clearly documented.

Eleutherodactylus rucillensis faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited montane range. The species' extremely restricted distribution makes it particularly vulnerable to environmental changes, with deforestation and land conversion eliminating critical breeding and foraging areas. Climate change poses an additional threat by altering the temperature and humidity conditions essential for this moisture-dependent amphibian's survival.

Threat summary

Habitat

This species inhabits montane forests and cloud forest environments at elevations between 800-1,200 meters in the mountains of Puerto Rico. It requires humid, well-vegetated areas with adequate leaf litter and moisture retention for breeding and shelter.
