Alsophis antiguae is the rarest snake in the genus Alsophis. This snake once occurred on Antigua and Barbuda, but by 1995, only 50 individuals remained on Great Bird Island, off the coast of Antigua.[2] Following the removal of invasive alien predators and successful reintroductions to a further three islands (Rabbit in 1999, Green Island in 2001, and York Island in 2008), the total population has increased to more than 1,000 individuals.[3]
Snakes of the genus Alsophis are all relatively small, usually less than about 1 m (39⅜ in) in body length. Females tend to be larger than males. these racers are rear-fanged, with enlarged teeth at the rear of their upper jaws.
Alsophis species are harmless to humans and most have a gentle temperament. They are diurnal, usually active from dawn to dusk.
