The largest African snake – the python – is fairly common, but difficult to see. It can grow up to five metres in length and kills its prey by wrapping its body around the victim and crushing it. It’s very rare to come across snakes in Kruger, even during the guided wilderness walks.
Snakes tend to shy away from humans and only attack if they’re caught by surprise. Nonetheless, one should be cautious at camps and lookout points. If you come across a snake in a camp, please alert the camp staff immediately.
Other notable reptiles in Kruger are two species of monitor lizards (leguaans), the water and the rock monitors. The water leguaan can be up to two metres long and is found at permanent water sources in Kruger. It feeds mainly on fish, crabs, mussels, small animals and birds.
Rock monitors can be found quite far from water in rocky outcrops and crevices. They grow up to 1,5m and feed on small mammals, birds, eggs, other reptiles and insects.
