Serpentes

(Snakes)

Snakes are elongated limbless reptiles of the suborder Serpentes.

Living snakes are found on every continent except Antarctica, and on most smaller land masses; exceptions include some large islands, such as Ireland, Iceland, Greenland, and the islands of New Zealand, as well as many small islands of the Atlantic and central Pacific oceans.

Family : Colubridae

With 249 genera, Colubridae is the largest snake family. Colubrids are a very diverse group of snakes. They can exhibit many different body styles, body sizes, colors, and patterns. They can also live in many different types of habitats including aquatic, terrestrial, semi-arboreal, arboreal, desert, mountainous forests, semi-fossorial, and brackish waters.

A primarily shy and harmless group of snakes, the vast majority of colubrids are not venomous, nor do most colubrids produce venom that is medically significant to mammals.

Genus : Oligodon (Kukri Snakes)

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 cut open eggs as they are being swallowed by the snake, allowing for easier digestion.
