Oligodon
''Oligodon'' is genus of colubrid snakes that was first described by the Austrian zoologist Fitzinger in 1826.〔 This genus is widespread throughout central and tropical Asia.
==Description==
''Oligodon'' is also known as kukri snakes. They are egg eaters and are usually under 90 cm (35 in) in length; different species display widely variable patterns and colorations. They subsist mostly by scavenging the eggs of birds and reptiles. Besides eggs, species of this genus also feeds on lizards, frogs, and small rodents.
''Oligodon'' is a rear-fanged snake genus. They have a set of enlarged teeth placed in the back of their mouths, as well as functional Duvernoy's glands. They are not dangerous to humans, though. Bites by some species have been reported to bleed excessively, suggesting presence of anticoagulants in the Duvernoy's gland secretions. Species of ''Oligodon'' are mostly nocturnal, and live on the floor of mature forests.
The common name of the genus comes from the kukri, a distinctively shaped Nepalese knife, which is similar in shape to the broad, flattened, curved hind teeth of ''Oligodon'' species. These teeth are specially adapted for their main diet of eggs; the teeth slit open eggs as they are being swallowed by the snake, allowing for easier digestion.
