Overview

Hyperolius jynx is a species of frog in the family Hyperoliidae. It is endemic to the Rumpi Hills in south-western Cameroon. The common name smooth egg-guarding frog has been proposed for this species.

The smooth egg-guarding frog faces severe population declines due to habitat destruction from deforestation and agricultural expansion throughout its limited range. Climate change is altering precipitation patterns critical for breeding, while the deadly chytrid fungus continues to devastate amphibian populations across its habitat.
