Overview

Strabomantis anomalus is a species of frogs in the family Strabomantidae. It is found in the Chocoan rainforests from near sea level to elevations of 1,180 m (3,870 ft) in northwestern Ecuador and western Colombia.

Strabomantis anomalus faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its restricted Colombian range. The species' extremely limited distribution makes it particularly vulnerable to localized threats, with deforestation for cattle ranching and crop cultivation fragmenting its remaining forest habitat. Climate change poses an additional threat by altering the moisture and temperature conditions essential for this amphibian's survival.

Threat summary

Habitat
