The Argentine black and white tegu is an impressive species of large, carnivorous reptile. Native to South America, it has become increasingly popular in both the pet trade industry and as a research subject for its unique behaviors, anatomy, and intelligence. This article will provide an overview of this remarkable species, including facts about its biology, behavior patterns, and conservation status.

Tegus are part of the family Teiidae which consists primarily of lizards that inhabit tropical regions across much of Central and South America.

The Argentine black and white tegu is one particular species within this group with two subspecies that occur in different parts of Argentina: Tupinambis merianae nigropunctatus (black-and-white) and T. m. duseni (striped). These animals vary in size but generally reach up to 4 feet long from snout to tail tip when fully grown. They have short legs relative to their body length compared to other lizard groups and are typically tan or grayish brown on top with light colored stripes along the back paired with either dark spots or stripes running down their sides.

Argentine black and white tegus demonstrate complex social behaviors like forming hierarchies among males during breeding season as well as parental care shown by females following egg deposition. In terms of diet they consume plants, insects, small mammals such as mice, eggs from birds’ nests – even carrion if available – making them opportunistic feeders capable of taking advantage of whatever food source might present itself at any given time.

They also possess some level of vocal communication which may be used between mates or while competing over resources amongst themselves. Despite being listed as Least Concern on the IUCN Red List due largely to their wide range throughout most of central Argentina there is still cause for concern regarding potential habitat loss due to human developments occurring near known populations.
