Tegutsevas

Tegutsevas, also known as *tegu* or *tegu lizards*, are a group of medium to large lizards belonging to the genus *Tupinambis*, part of the family Teiidae. Native to South America, these reptiles are primarily found in Argentina, Brazil, Paraguay, Uruguay, and parts of Bolivia and Peru. Tegutsevas are known for their robust build, distinctive coloration, and adaptability to various environments, including forests, grasslands, and even urban areas.

Tegutsevas exhibit sexual dimorphism, with males typically larger and more brightly colored than females. They possess a sturdy body, a long tail, and strong limbs adapted for both climbing and terrestrial movement. Their coloration varies widely, ranging from shades of brown and gray to vibrant yellows and greens, often with darker markings. Some species, like the Argentine black tegu (*Tupinambis teguixin*), are primarily dark, while others, such as the yellow tegu (*Tupinambis merianae*), display more vivid hues.

These lizards are omnivorous, feeding on a diet that includes insects, small vertebrates, fruits, and vegetation. Tegutsevas are also known for their intelligence and problem-solving abilities, often using tools in captivity to access food. They are live-bearing, giving birth to live young rather than laying eggs, and mothers may exhibit maternal care by guarding their offspring for short periods.

In some regions, tegutsevas are considered pests due to their tendency to raid crops, particularly corn and citrus fruits. However, they are also valued for their role in controlling insect populations and are sometimes kept as pets by reptile enthusiasts. Conservation status varies by species, with some populations facing threats from habitat loss and hunting, though many tegutsevas remain common in their native ranges.

Due to their hardiness and adaptability, tegutsevas have occasionally been introduced to other continents, including the United States and parts of Europe, where they may establish feral populations. Their presence in non-native areas can have ecological impacts, though they are not currently listed as globally threatened.
