Crossodactylus grandis

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Crossodactylus grandis faces severe population decline primarily due to habitat destruction from urban expansion and agricultural conversion in Brazil's Atlantic Forest region. The species' dependence on pristine stream environments makes it particularly vulnerable to water pollution and sedimentation from nearby human activities. Climate change compounds these pressures by altering precipitation patterns that affect the rocky stream habitats essential for this frog's reproduction and survival.

Threat summary

Habitat

This species inhabits rocky streams and adjacent riparian forests within Brazil's Atlantic Forest biome, typically found in areas with fast-flowing water and boulder-strewn creek beds. It requires pristine aquatic environments with stable water flow and minimal human disturbance for successful breeding and larval development.
