Argentine White and Black Tegu Care Sheet

Native to the subtropical and temperate regions of Argentina and parts of Brazil, Argentine Black and White Tegus are adapted to a wide range of environments. They can thrive in both forested areas and savannas, displaying a degree of adaptability that’s truly admirable. This adaptability is reflected in their behavior and care needs as captive pets.

In the wild, these tegus are usually found in burrows, which offer them protection from predators and help regulate their body temperature. They’re most active during daylight hours and are known to be quite agile and swift movers. This behavior translates to their captive environment as well, with tegus often enjoying a good amount of space to roam and explore.

Argentine Black and White Tegus are known for their intelligence and inquisitive nature. They show a high degree of interaction with their environment, often exploring their surroundings with keen interest. This curious and active behavior makes them fun to observe and engage with.

The females, on the other hand, tend to be a bit smaller, usually reaching lengths of up to 3 feet. Their impressive size is indeed one of the traits that sets them apart from many other pet reptiles.
