The King Cobra is the world's longest venomous snake,with a length that can be as large as 6.7 m (22 ft).This species is widespread throughout Southeast Asia and parts of India,but found mostly in forested areas. The skin is either olive-green,tan or black and it has faint,pale yellow cross bands down the length of the body.The belly is cream or pale yellow, and the scales are smooth.The head of a mature snake can be quite massive and bulky in appearance,though like all snakes,they can expand their jaws to swallow large prey items.
It has proteroglyph dentition,meaning it has two short,fixed fangs in the front of the mouth which channel venom into the prey like hypodermic needles.The male is larger and thicker than the female. It lives in dense highland forests.The snake has a preference for living in areas dotted with lakes and streams.King Cobra populations have dropped in some areas of its range due to the destruction of forests,but despite this the snake. King Cobra's venom is primarily neurotoxic and thus attacks the victim's central nervous system and quickly induces severe pain, blurred vision,vertigo,drowsiness,and paralysis.
