Nile monitors have a varied diet including small aquatic vertebrates, bird’s eggs and chicks, aquatic invertebrates and crocodile eggs. They are a major predator of crocodile eggs and in some cases the main threat to crocodile populations in nature/game reserves. They are common in the Okavango Delta
Breeding: they frequently lay their eggs in termite mounds. During summer they dig a hole in the mound, lay their eggs and then leave, often without covering the hole. The termites close up the hole thus affording protection to the eggs as well as providing both thermo regulated environment and humidity. The young hatch and dig their way out of the mound.
