The Argentine black and white tegu (Salvator merianae), also commonly known as the Argentine giant tegu, the black and white tegu, the blue tegu, and the huge tegu, is a species of lizard in the family Teiidae. The species is the largest of the "tegu" lizards. It is an omnivorous species, which inhabits the tropical rain forests, savannas, and semideserts of eastern and central South America. It is native to south and southeastern Brazil, Uruguay, eastern Paraguay, Bolivia, and Argentina. Tegu lizards are sometimes kept as pets, being notable for their unusually high intelligence and their relatively gentle nature. Like some reptiles, tegus enter brumation in autumn when ambient temperature drops. Wikipedia →
