Alsophis
''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. 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. Following the removal of invasive alien predators and successful reintroductions to a further three islands (Rabbit in 1999 ...

Alsophis Antillensis
''Alsophis antillensis'', the Guadeloupe racer, Antilles racer, or Leeward racer, is a species of snake endemic to the Caribbean island of Guadeloupe. Description It can reach nearly a meter in length. It feeds on lizards and small rodents. It rarely bites humans, but may release a foul-smelling (though harmless) cloacal secretion when disturbed. Taxonomy ''Alsophis sibonius'' from Dominica and ''Alsophis manselli'' from Montserrat were previously considered subspecies, but are now considered their own species.

Leeward Island Racer
The Leeward Island racer (''Alsophis rijgersmaei'') is a species of snake in the family Colubridae. The species is found in Anguilla, Saint Barthélemy, and is probably extirpated from Sint Maarten. Taxonomy It was named by Edward Drinker Cope in 1869, the specific name honouring the Dutch government physician in St. Maarten, Hendrik Elingsz van Rijgersma, who was an avid amateur naturalist.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("''Alsophis rijgersmai'' ic, p. 222). Conservation It was thought to have been eradicated by the mongoose (Westerman, 1955; Sajdak and Henderson, 1991 in Powell et al., 1992). However, in 1992 there was a report of five specimens that were captured at Mary's Fancy, and in the same year one was observed in the field (Powell et al., 1992). A snake was also seen after the hurricane in January 1996 during a field trip at Flagstaf (Ecovisio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alsophis Antiguae
The Antiguan racer (''Alsophis antiguae'') is a harmless rear-fanged (opisthoglyphous) grey-brown snake that was until recently found only on Great Bird Island off the coast of Antigua, in the eastern Caribbean. It is among the rarest snakes in the world. However, in the last 20 years, conservation efforts have boosted numbers from an estimated 50 to over 1,100 individuals by eradicating non-native predators and reintroducing the snake to other Antiguan islands in its original range. In addition to Great Bird Island, the Antiguan racer has successfully recolonised the nearby Rabbit Island, Green Island, and York Island. Taxonomy The Antiguan racer is a snake that belongs to the family Dipsadinae, which includes about half of the world's known snake species. It belongs to the genus ''Alsophis'', which contains several species of West Indian racers. Many West Indian racers are threatened or extinct. Description This racer exhibits sexual dimorphism.

Taxonomy Along with '' Alsophis sibonius'' from Dominica, it was previously considered a subspecies of ''Alsophis antillensis ''Alsophis antillensis'', the Guadeloupe racer, Antilles racer, or Leeward racer, is a species of snake endemic to the Caribbean island of Guadeloupe.

Alsophis Rufiventris
The red-bellied racer (''Alsophis rufiventris'') is a species of Colubrid snake that is endemic to the Lesser Antilles in the Caribbean, where it is found on the islands of Saba, Sint Eustatius, Saint Kitts, and Nevis.

Dipsadinae
Dipsadinae is a large subfamily of colubroid snakes, sometimes referred to as a family (Dipsadidae). They are found in most of the Americas, including the West Indies, and are most diverse in South America. There are more than 700 species. Dipsadinae are an ecologically and morphologically diverse group of mostly small to moderate-sized snakes (typically less than in total length). Some are arboreal, but others are aquatic or terrestrial and may even burrow. Most are oviparous. Many eat frogs or lizards, and some consume mammals and birds. Several genera (e.g. '' Adelphicos'', '' Atractus'', ''Geophis'', ''Dipsas'', ''Ninia'', '' Sibon'', ''Sibynomorphus'', ''Tropidodipsas'') are specialized feeders on gooey and slimy prey, such as frog eggs, earthworms, snails, and slugs. Almost all species are completely harmless to humans, although a few genera (e.g. ''Borikenophis'', '' Cubophis'', ''Heterodon'', ''Hydrodynastes'', ''Philodryas'') have inflicted painful bites with local, no ...

Great Bird Island
Great Bird Island is a tiny islet lying almost three kilometers north-east of Antigua. Measuring just , it is smaller than most city parks. It is a private island but open to the public. Flora and Fauna The island is the only place on Earth where you can see an Antiguan racer (''Alsophis antiguae'') in the wild. The entire world population of this snake no longer lives on just the one island. Named by sailors who were amazed at the number of birds that they found living and nesting there, Great Bird Island is a miniature paradise. As well as being the last refuge of the Antiguan racer, it is also home to a variety of other endangered creatures including the near-threatened lizard '' Pholidoscelis griswoldi'', brown pelicans (''Pelecanus occidentalis''), West Indian whistling ducks and red-billed tropicbirds (''Phaethon aethereus'').Bob DowninAntigua offers 365 beaches full of sand, sights and water sports for travelers ''Akron Beacon Journal'' Jul 10, 2011 Hundreds of black r ...

Colubridae
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.
