There are several species of monitor lizards in the world and can found across Africa, southern and southeastern Asia, the Pacific Islands and some parts of northern Australia.
Classified as iguanid lizards, (perhaps) the most famous of these is the Komodo dragon – a fearsome animal and the largest lizard in the world. Adult Komodo dragons can weigh up to 198 pounds (90 kg) and can grow to 3 meters (10 feet). They are extremely powerful animals and can, individually, kill deer and water buffalo. In addition, its bite is venomous – it has toxins that prevent the blood from clotting and lowers blood pressure.
Monitor lizards, as a species, have excellent eyesight and sense of smell. They can also manage their water needs intelligently, if they live in dry areas.
