Physalaemus angrensis

Unknown

Overview

Physalaemus angrensis is a species of frog in the family Leptodactylidae. It is endemic to the Atlantic Forest of the Rio de Janeiro state in southeastern Brazil. It is a small frog, and is reported to have a similar call to its congener, P. moreirae.

Physalaemus angrensis faces severe threats from rapid urban expansion and infrastructure development within its extremely limited range in the Atlantic Forest of Rio de Janeiro state. The species' restriction to a few small forest fragments makes it particularly vulnerable to habitat fragmentation and edge effects. Water pollution from urban runoff and agricultural activities poses additional risks to the aquatic breeding sites essential for this frog's reproduction.

Threat summary
