A large, highly venomous snake, the Indian cobra feeds on rodents, lizards and frogs. As well as biting, the Indian cobra can attack or defend itself from a distance by "spitting" venom, which, if it enters the opponent's eyes, causes severe pain and damage. The snake actually forces the venom through its fangs, by exerting muscular pressure on the venom glands, so that it sprays out in twin jets for 2 m (6 1/2 ft) or more. In its characteristic threat posture, the Indian cobra raises the front one-third of its body and spreads out its long, flexible neck ribs and loose skin to form a disc-like hood, on the back of which there are markings resembling eyes. Indian cobras pay more attention to their eggs that is usual in snakes. The 8 to 45 eggs (usually 12 to 20) are laid in a hollow tree, a termite mound or earth into which the snakes tunnel. The female guards the clutch throughout the incubation period, leaving them only for a short time each day to feed. The young hatch after about 50 or 60 days.
