description Harlequin Frog Overview
Harlequin frogs comprise the genus Atelopus, a group of brightly colored amphibians native to Central and South America. These stream-dwelling anurans are typically small and diurnal, relying on their vibrant patterns to warn predators of their toxicity. Since the 1980s, dozens of species within this genus have experienced severe population declines due to the fungal disease chytridiomycosis. Consequently, many are now classified as critically endangered or extinct.

help Harlequin Frog FAQ
What has caused the rapid decline of harlequin frog populations since the 1980s?
Since the 1980s, dozens of harlequin frog species (genus Atelopus) have been driven to the brink of extinction. This massive die-off is primarily linked to the spread of the deadly chytrid fungus and changing climate conditions.
Where are harlequin frogs natively found?
Harlequin frogs are a group of brightly colored amphibians native to the tropical regions of Central and South America. They are typically found in small, specific ranges, often near fast-flowing mountain streams.
Why do harlequin frogs have such vibrant, contrasting colors?
These stream-dwelling anurans rely on their vibrant, highly contrasting patterns to warn predators of their toxicity. This biological warning sign, known as aposematism, lets predators know that their skin contains harmful tetrodotoxins.
Are harlequin frogs active during the day or night?
Unlike most frog species, harlequin frogs are strictly diurnal, meaning they are most active during the daytime. Their bright warning colors allow them to forage for insects in the daylight without relying on the cover of darkness.
