Invasive Argentine Tegu Lizard Population Alarms Southeastern Wildlife Experts

Wildlife specialists in Florida, Georgia, and South Carolina are increasingly concerned about the growing presence of the Argentine black and white tegu, an invasive reptile species native to South America. Unlike other established exotic species such as iguanas and snakes, the tegu poses a important environmental threat due to its adaptability and high reproductive rate.
Tegu’s Growing Range and Impact
The Argentine tegu, capable of reaching lengths exceeding 3 feet and weighing over 8 pounds, has established itself in several southeastern ecosystems. According to USA Today, local authorities believe the lizards were initially introduced through the exotic pet trade and have since expanded their range into natural, urban, and agricultural areas.
Description and Behavior
Tegus are robust lizards characterized by black and white speckled skin and banded patterns across their bodies. While they primarily move on land and are not adept climbers, they are proficient swimmers. Young tegus often exhibit shining green coloration on their heads, which fades with age. The species is native to the warm, dry regions of Argentina.
Defensive Nature and diet
While not inherently aggressive,tegus can become defensive if they feel threatened. The Georgia Wildlife Office notes that tegus possess sharp teeth and a powerful jaw, and may use their tail as a warning signal. The primary concern among wildlife specialists is the tegu’s diet, as they consume native species, including the eggs of ground-nesting birds like turkeys and quail, as well as those of protected reptiles such as the American alligator and gopher tortoise.
Reproductive Capacity and lifespan
The tegu’s high reproductive capacity is another cause for concern. Females can lay up to 35 eggs in the spring, which incubate for approximately 60 days. With a lifespan exceeding 20 years,tegus have a significant opportunity to impact local ecosystems. They also undergo a period of brumation,similar to hibernation,during the late fall and winter,sheltering in burrows.
Confirmed Populations and Locations
Established Argentine tegu populations have been identified in several counties. In Florida, these include Miami-Dade and St. Lucie. In Georgia, a state university study documented at least 43 confirmed reports, with the highest concentrations in Tattnall, Toombs, and Gwinnett counties.
Control Measures and Regulations
Regulations in Florida and georgia permit the capture or elimination of tegus on private land with the owner’s permission. Hunting with firearms is also allowed in designated public areas during specified seasons. Authorities emphasize the importance of humane dispatch methods and recommend the use of traps.
Reporting Sightings
Residents of affected states are encouraged to report tegu sightings, including a photograph and location details. In Georgia, reports can be submitted through gagressives.org or by calling (478) 994-1438. In Florida, sightings can be reported by calling 888-483-4681 or through the IveGot1 submission.
