Union Island Gecko

Gonatodes daudini

Stable

Overview

Gonatodes daudini, also known commonly as the Grenadines clawed gecko or the Union Island gecko, is a species of lizard in the family Sphaerodactylidae. The species is endemic to Union Island in Saint Vincent and the Grenadines.

Gonatodes daudini faces severe threats from habitat destruction due to urban expansion and agricultural development in its extremely limited range in Venezuela. The species' restriction to a tiny geographic area makes it exceptionally vulnerable to any environmental changes or human activities. Mining operations and infrastructure development pose additional pressures on the remaining habitat fragments where this gecko persists.

Threat summary

Habitat

This gecko inhabits dry forest and scrubland environments in the coastal regions of northern Venezuela. It appears to prefer areas with rocky outcrops and sparse vegetation typical of xeric habitats in the Caribbean coastal zone.
