A Tegu is a from a group of lizards belonging to the Tangae family. Their native place is South America and Central America and they have diverse habitats. They are famous for their big size and for preying on others. Some of these species have gained economic importance as pets and others as food. A few species have invaded the provinces of south Florida. Even though they show a resemblance to monitor lizards, they are only distantly related. It is due to the convergent evolution that they exhibit similarity.
Most of the species have a black background. A few of them have bands across their back, colored white, red or yellow. And a few have lines running down their body with unsymmetrical patterns on their body.. The Tegu lizard has tiny square scales displayed in regular rings round the body. The large lizards have streamlined bodies, powerful legs and a long tail. The length of the majority of them is one meter (3 feet). Similar to other teiids, the Tegu uses its tongue and a unique organ located at the roof of its mouth called the Jacobson’s organ to detect and differentiate the chemical cues connected with their prey and other lizards.
The habitat of tegus is wide spread in the Savannas, Amazon rain forests and deciduous, partially dry thorn forests.
