Vanzolini's Teiid

Colobodactylus dalcyanus

Unknown

Overview

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

Colobodactylus dalcyanus faces severe threats from habitat destruction due to urban expansion and agricultural conversion in its restricted Atlantic Forest range. The species' extremely limited distribution makes it particularly vulnerable to localized disturbances, while its specialized microhabitat requirements in leaf litter and forest floor environments are easily disrupted by human activities. Climate change poses additional risks through altered precipitation patterns that could affect the humid conditions essential for this gecko's survival.
