Among the great variety of snakes found in India, some are very dangerous and others are completely harmless. As a part of the food chain, snakes, together with other reptiles, play a very important role. They are also among the key natural rat and mouse population controllers. If not managed, rodents could heavily damage the crops and also transmit human diseases. However, on the other hand, a few species of snakes are very venomous and their bite can even lead to death if proper treatment is not given on time.
