Haitian Worm Snake

Typhlops tetrathyreus

Declining

Overview

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

Typhlops tetrathyreus faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in the Caribbean. The species' fossorial lifestyle makes it particularly vulnerable to soil disturbance and chemical contamination from pesticide use. Its restricted distribution and specialized underground habitat requirements leave little room for population recovery when local extinctions occur.

Threat summary

Habitat

This fossorial blind snake inhabits loose, well-drained soils in tropical dry forests and scrublands of the Caribbean region. It prefers areas with organic-rich substrates where it can burrow effectively to hunt for small invertebrates, particularly in leaf litter zones and beneath fallen logs.
