The island worm snake (Typhlops sulcatus)[1] is a species of snake in the Typhlopidae family.[2]
It is endemic to southwestern Hispaniola (Dominican Republic and Haiti), formerly including Navassa Island, an uninhabited island located in the Caribbean.[3]
It has been rated Near Threatened. It is extirpated from Navassa Island, where the species became a casualty of human interference and feral predators, such as rodents, cats, dogs and goats that were introduced during the large-scale mining period on this small island during the 1800s.
