Barbados Threadsnake

The Barbados threadsnake holds the distinction of being among the smallest snake species known to science, with adults reaching only about 10 cm in length, thin enough to be compared to a strand of spaghetti. It is endemic to the small island of Barbados and was formally described as a distinct species in 2008.

Due to its extremely limited range and habitat loss on Barbados, it is considered critically endangered. It is entirely harmless to humans and virtually never encountered due to its minute size and fossorial habits.

• Extremely small, thread-like body, among the thinnest and shortest of any snake species
• Glossy grayish-brown to dark brown dorsal coloration, often with faint yellowish dorsal lines
• Tiny, vestigial eyes
• Smooth, tightly overlapping scales
• Blunt head barely wider than the neck
• Adults reach only about 10 cm (4 in) in length

Restricted entirely to the island of Barbados in the eastern Caribbean, where it inhabits leaf litter and moist soil in the small remaining patches of forest. Its extremely limited range and the island's heavily developed and deforested landscape make it one of the rarest and most range-restricted snakes in the world.

Nocturnal and fossorial, spending nearly all of its time in soil or leaf litter, foraging for termite and ant larvae, eggs, and pupae. Because of its minute size, it is rarely observed even where present.

Believed to lay a single, relatively large egg per clutch, an unusual reproductive strategy linked to its extremely small body size.
