The Argentine black-and-white or giant Argentine tegu (), native to South America, was brought to Florida for the pet trade and has become established in three areas of Florida: southern Miami-Dade County, southwest Charlotte County, and west-central Hillsborough County. Individual lizards belonging to this species and two other tegu species have also been captured across the Florida peninsula, with several credible records also from the Panhandle. These large lizards grow to 4–5 feet long. Argentine black-and-white tegus eat native reptiles and their eggs, and likely also consume the eggs and young of ground-nesting birds. Tegus could negatively impact threatened and endangered species, including gopher tortoises. Tegus have been observed eating alligator eggs and could be a problem for threatened American crocodiles in southern Florida. They are opportunistic predators and consume a variety of small prey as well as plant matter and carrion (dead animals). In west-central Florida, black-and-white tegus inhabit dry, upland areas with sandy soils, including natural, urbanized, and agricultural areas. In southern Florida, they occur in densely vegetated areas along canals and roadsides. Tegus could potentially become an agricultural pest or a source of bacterial contamination of food crops. These lizards may dig their own burrows but also invade the burrows of native species, such as gopher tortoises. Tegus remain underground during late fall and winter months, even in southern Florida. Female Argentine black-and-white tegus in south Florida lay approximately 30 eggs per clutch in the spring and summer. They may live 15–20 years
