Kukri snakes are a part of the genus Oligodon of the species of Colubridae found mostly in central and tropical Asia. This genus Oligodon is known usually as Kukri snakes and has more than 70 related and recognized species in the same genus. These snakes range all over Asia, with more than 20 species living in states which range in most parts of India. Although most species of the snakes survive on different bird and reptiles' eggs, some of the Oligodon family members are also known to use their sharp teeth to feed on the internal organs of toads. Read on to find out more about this!

The name Kukri is derived from a Nepalese knife. The knife is curved and broad, similar to the hind teeth of the Oligodon species which are broad, flattened, and curved. The rear-fanged Oligodon species is not fatal for humans as they are non-venomous, but the bites from these species can be seriously injurious and can bleed extensively due to their sharp enlarged teeth in the back of their mouths and also the presence of Duvernoy's gland, which has anticoagulants.

The most seen kukri snakes in the world are the Common kukri snake/Banded kukri (Oligodon arnensis) and the Small banded kukri snake (Oligodon fasciolatus). Snakes found all over the world have a lot of different features differentiating them. Read about the King Brown snake and the King Rat snake, the kings of the snakes, here on the Kidadl website.
