The Nile Monitor is a species of monitor lizard from the savannas of Africa. It is the largest lizard in all of Africa, as well as the heaviest. It has a long neck, powerful tail and claws, and well-developed limbs. It is carnivorous in nature, often going after the eggs of the Nile crocodile. It is oviparous, laying around ten eggs, though larger females can lay more. Nile Monitors often cover their eggs with soil or protect them in a hollow tree stump. They have even been known to burry their eggs in termite mounds. As the termite work to repair the break in caused by the burrowing mother, they seal the eggs inside, protecting them from predators. Once the eggs hatch, the eat the termites until they are strong enough to burrow out of the mound.

The Nile Monitor has been observed to cooperate when foraging. One varanid lures the female crocodile away from her nest while the other opens the nest to feed on the eggs. The decoy then returns to also feed on the eggs.
