Overview

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

Sphaerodactylus callocricus faces severe threats from habitat destruction due to urban development and tourism infrastructure expansion across its extremely limited range in the Caribbean. The species' tiny population size makes it highly vulnerable to stochastic events, while introduced predators such as cats and rats pose additional pressure on this ground-dwelling gecko. Climate change-induced sea level rise and increased hurricane intensity further threaten the coastal and low-elevation habitats where this species occurs.

Threat summary

Habitat

This diminutive gecko inhabits dry coastal forests, scrublands, and rocky areas with dense leaf litter and low vegetation cover. The species is typically found in microhabitats under rocks, fallen logs, and within root systems of native plants in areas with well-drained soils.

Frequently asked questions

Why is Sphaerodactylus callocricus classified as Critically Endangered?
Sphaerodactylus callocricus 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. Sphaerodactylus callocricus faces severe threats from habitat destruction due to urban development and tourism infrastructure expansion across its extremely limited range in the Caribbean. The species' tiny population size makes it highly vulnerable to stochastic events, while introduced predators such as cats and rats pose additional pressure on this ground-dwelling gecko. Climate change-induced sea level rise and increased hurricane intensity further threaten the coastal and low-elevation habitats where this species occurs.
Where does Sphaerodactylus callocricus live?
Sphaerodactylus callocricus occurs in Dominican Republic, and Haiti. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sphaerodactylus callocricus?
The main threats to Sphaerodactylus callocricus are 1.1, 1.3, 2.1, and 5.1. The full IUCN-classified threat record for this species is detailed on the species page.
