Alsophis antiguae, commonly known as the Antiguan racer, is a non-venomous snake found only on the Caribbean islands of Great Bird Island, Rabbit Island, and Green Island off the coast of Antigua. Measuring up to 1 meter in length, it's characterized by its slender body and distinctive brown and olive coloration. The species plays a crucial role in controlling the populations of invasive rodents and lizards.

Alsophis antiguae, commonly known as the Antiguan racer, is native to the Caribbean island of Antigua and its satellite islands, notably Great Bird Island. This species was historically widespread on Antigua but is now limited to a few offshore islets due to habitat loss and the introduction of invasive species.

The typical habitat of the Antiguan racer is coastal and dry tropical forests on small islands. These areas are characterized by a warm climate with average temperatures ranging from 25°C to 30°C (77°F to 86°F) and a distinct wet and dry season pattern. Vegetation typically includes shrubs, grasses, and sparse trees, providing cover and hunting grounds for the species.

Alsophis antiguae primarily occupies the ecological niche of a terrestrial predator, feeding on small reptiles such as lizards. The snakes are well-adapted to hunting in leaf litter and underbrush, using their agile bodies to navigate through dense vegetation. This adaptation allows them to exploit the available prey resources effectively on the limited land area of their habitat.
