Snakes are found on every continent except Antarctica and come in two varieties - poisonous and non-poisonous. Some of the most dangerous poisonous snakes mentioned are the Krait, Cobra, and Viper. The Krait is one of the most venomous snakes. Cobras are known for their distinctive hoods and neurotoxic venom. Vipers can be pit or pitless varieties. Non-poisonous snakes included the large python and rat snake, which is sometimes called a farmer's friend for controlling rodent populations. While some snakes are worshipped in India, they are also eaten as food in other parts of Asia.
