A Fine Line on the Barbados Threadsnake
The Barbados threadsnake (Tetracheilostoma carlae) is a species of snake endemic to the Caribbean island of Barbados. They are found primarily in dry tropical forests, hiding under leaf litter or in loose soil. Like most threadsnakes, the Barbados threadsnake is fossorial, residing almost entirely underground.
T. carlae's greastest claim to fame is that it is the world's smallest known species of snake. Adults are only 10 cm (3.94 inches) in length and weigh 0.6 g (0.02 ounce) on average. Individuals tend to be dark brown with orange or yellow stripes running down their sides; this coloration allows them to blend in with their surroundings. The eyes are also notably diminished, as Barbados threadsnakes are almost completely blind.
The Barbados threadsnake's diet consists almost entirely of small insects, particularly termites and termite larvae. Thanks to their small size, they are able to easily infiltrate termite nests and remain relatively undetected while they eat. Little is known about the common predators of T. carlae, but they likely include larger insects such as centipedes and spiders, as well as lizards and birds.
It is unknown exactly when Barbados threadsnakes mate, but females produce one clutch consisting of only one egg every year. However, hatchlings are quite large in proportion to their mother, emerging at about half of their full-grown length.
Conservation status: The Barbados threadsnake is classified as Critically Endangered by the IUCN. They are threatened primarily by habitat loss, as much of Barbados' natural forests have been destroyed. They may also face increased competition from the introduced Brahminy blind snake.
