A large, eye-catching lizard native to central South America, particularly found in regions of Paraguay, northern Argentina, Bolivia, and parts of Brazil. It’s closely related to the black and white tegu (Salvator merianae) and shares many of its cousin’s characteristics, but what sets the red tegu apart is its distinct reddish coloration, which can range from dusty rose to deep brick red—especially in adult males, who develop the most vivid hues during breeding season. This striking color, combined with their size and intelligence, makes red tegus one of the most charismatic reptiles in their range.
Like other tegus, the red tegu is a terrestrial, diurnal species, meaning it’s active during the day and spends most of its time on the ground. They’re often seen basking in the sun or digging into loose soil to forage or burrow. Red tegus are excellent diggers, using their strong claws to excavate shelters or locate food underground.
Red tegus are omnivores with a wide-ranging diet. They eat insects, snails, eggs, small vertebrates, fruits, and vegetables, and they’ll scavenge carcasses when available. This flexible diet helps them survive in both wild and human-altered environments, including farmlands and forest edges.
One especially cool trait of the red tegu is its seasonal endothermy. During the reproductive season, they can raise their body temperature slightly above their environment—unusual for cold-blooded animals. This allows them to stay more active in cooler conditions and may help in egg development or early spring foraging.
Red tegus have become popular pets due to their intelligence and, with consistent handling, their potential for docility and tameness—though they need large enclosures, warm conditions, and varied diets to thrive. However, in regions like Florida, escaped or released pet tegus have formed invasive populations, posing a threat to native wildlife by eating bird eggs, reptiles, and even endangered species.
