The Collared Tree Lizard is also called the Harlequin Racerunner, both named after the animal's appearance with a black
collar and a colourful and patterned skin. Native to northern South America, its head is red and body green, similar to the larger
Caiman Lizard from the same region.
The green patterned body gives good camouflage in its treetop habitat. The male is more strongly coloured red than the female.
An adult is around 6 inches in length. Eggs are laid on the ground and the hatchling bursts out of the egg and starts running.
