The Savannah/Bosc's Monitor is the most aggressive member of the monitors in Africa.

Bosc’s Monitors exhibit an unusual defence posture. If they are confronted by a snake or another animal too large to overpower, the lizard may roll onto its back, grasping its hind leg in its mouth. The ring of lizards apparently makes swallowing to much of an effort for a would be predator.

In 1984 alone, over 1,000,000 hides from this species legally entered the United States. It is a sad indictment against humans that they are intent on exterminating a species which helps control crocodiles, venomous snakes, vermin populations and which eats carrion.
