Alsophis is a genus of snakes in the subfamily Dipsadinae of the family Colubridae. Species in the genus Alsophis are among those snakes commonly called "racers". Alsophis species are endemic to the Lesser Antilles in the Caribbean. One species in the genus Alsophis, A. antiguae, is one of the world's rarest known snakes. Snakes of the genus Alsophis are small and rear-fanged, and they are considered harmless to humans. This genus contains nine described species which are recognized as being valid.[1] Several species once included in this genus have been placed in the genera Borikenophis and Pseudalsophis.
Rarest species
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]
Description
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.
Behavior
Alsophis species are harmless to humans and most have a gentle temperament. They are diurnal, usually active from dawn to dusk.
