African rock pythons can reach a length of five to six metres. Although they are not venomous they can deliver a nasty bite and hold their victim in a vice like grip whilst they begin to coil around it. They kill by constricting their prey. Larger specimens eat antelope and there have been several recordings of them eating humans. Pythons are well camouflaged so can be difficult to spot in the African bush.
