Musical Treefrog

Aplastodiscus musicus

Declining

Overview

Aplastodiscus musicus is a species of frog in the family Hylidae. It is endemic to Brazil. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss.

Aplastodiscus musicus faces severe population decline due to rapid deforestation and urban expansion within its restricted Atlantic Forest range in southeastern Brazil. The species' dependence on pristine forest canopy for breeding makes it particularly vulnerable to habitat fragmentation, as even small clearings can disrupt its reproductive cycle. Agricultural conversion and infrastructure development continue to reduce the remaining forest patches where this arboreal frog can survive.

Threat summary

Habitat

This species inhabits the upper canopy of primary Atlantic Forest (Mata Atlântica) in southeastern Brazil, particularly favoring areas with dense tree cover and high humidity. It requires intact forest structure for breeding, typically utilizing tree holes and bromeliad pools in the forest canopy.

Why is Musical Treefrog classified as Critically Endangered?
Musical Treefrog 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. Aplastodiscus musicus faces severe population decline due to rapid deforestation and urban expansion within its restricted Atlantic Forest range in southeastern Brazil. The species' dependence on pristine forest canopy for breeding makes it particularly vulnerable to habitat fragmentation, as even small clearings can disrupt its reproductive cycle. Agricultural conversion and infrastructure development continue to reduce the remaining forest patches where this arboreal frog can survive.
