Overview

The web-footed coqui, stream coqui, Puerto Rican stream frog, Karl's robber frog or coquí palmeado, is a possibly extinct Puerto Rican frog species in the family Eleutherodactylidae. It was first described by Chapman Grant in 1931, and was named after herpetologist Karl Patterson Schmidt. It is the largest Eleutherodactylus species of Puerto Rico.

Eleutherodactylus karlschmidti faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited Puerto Rican range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and natural disasters such as hurricanes. Invasive species and potential disease outbreaks pose additional risks to the remaining populations.

Threat summary

Habitat

Webbed-footed Coqui 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. Eleutherodactylus karlschmidti faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited Puerto Rican range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and natural disasters such as hurricanes. Invasive species and potential disease outbreaks pose additional risks to the remaining populations.
Where does Webbed-footed Coqui live?
Webbed-footed Coqui occurs in Puerto Rico, and United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Webbed-footed Coqui?
The main threats to Webbed-footed Coqui are 11.1, 5.2, 5.4, and 8.1. The full IUCN-classified threat record for this species is detailed on the species page.
