The Tegu refers to large, ground-dwelling lizards in the family Teiidae, with the most common species being the Argentine Black and White Tegu (Salvator merianae). Native to South America, especially Argentina, Brazil, and Paraguay, tegus are robust lizards known for their intelligence and docile nature in captivity. They can grow up to 1.2 to 1.5 meters (4 to 5 feet) in length, with distinctive black and white banding on their bodies. Tegus are omnivorous, feeding on fruits, vegetables, insects, small mammals, and eggs.
Highly adaptable, tegus are strong diggers and swimmers, often found in forests, savannas, and grasslands. In the pet trade, they are popular due to their ease of taming and inquisitive behavior, though they require spacious enclosures and proper care. Some species, like the Argentine and Colombian tegus, have become invasive in parts of the U.S., particularly in Florida.
