This highly venomous, 2 to 4 feet long snake, blends in with rainforests and swamps with its beautiful patterns and colours. It can puff up to twice its body size when excited and makes a loud hissing noise. They come out in the night and eat rodents, frogs and fish. These vipers live for 8 to 12 years.
