Overview

The cricket coquí, green coquí, or coquí grillo is a species of frog in the family Eleutherodactylidae endemic to Puerto Rico. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

Eleutherodactylus gryllus faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in Puerto Rico. The species' small population size and restricted distribution make it extremely vulnerable to environmental changes and human activities. Introduced predators and competitors further pressure remaining populations, while climate change may alter the specific microhabitat conditions this endemic frog requires for survival.

Threat summary

Habitat

This endemic Puerto Rican frog inhabits moist limestone forests and associated cave systems, typically found in areas with dense leaf litter and rocky crevices.
