These are the biggest and heaviest species of lizards! They have a very heavy-weighted tail and their tongue comes in and out every so often. They get their prey by blending into the environment and having a lot of patience. However, they are also very slow like the tortoise. They eat other dead animal remains, insects, birds and even snakes! You'll most likely find them on the five islands of southeastern Indonesia, which have rugged hills and is savanna grassland-like.
