There are two species of snakes which are endemic to Seychelles and another introduced that is rarely seen. All three are completely harmless and lives solitary lives within forests and around settlement where they feed on rodents and small invertebrates as well as birds, eggs and lizards.
A slender bodied snake which could attain a maximum body length of 120 centimeters, the species occurs in most habitats within the inner granitic islands of Seychelles. The wolf snake has a small head, relatively large eyes and a muzzle that is narrow and pointed and comes in varieties of color morphs.
A thick bodied snake which attains a length of 60-90 cm. It has a broad muzzle, small golden eyes and smooth scales on its body. The dorsal side of the snake is brown with three dark narrow stripes that run along the length of its body. Its ventral side is usually grey. The top of its head is brown and it has a white snout. Two white stripes run from behind the eyes to its neck. It is found on Mahé, Praslin, Fregate and Probably Silhouette.
This species was accidentally introduced with agricultural products during the 19th century and is now widespread on most granitic islands but also introduced to outer islands such as Assumption. The species has a life history that is very secretive as it is found within damp soil habitats. It is close in appearance to caecilians but has characteristics scale patterns that are typical of reptiles; it also has a small tongue and its head is typical of reptiles. This fossorial and parthenogenic snake is widely distributed in the tropics and many Caribbean, Indian and Pacific Ocean islands where it has been easily introduced. It has been recently reported around the gulf of Guinea and the Comoro islands.
