Miami Standard (Key Largo, FL) – The Florida Keys is the latest region to report a sighting of the Argentine black and white tegu, a giant invasive lizard species that experts warn could threaten native wildlife.

The Florida Keys National Wildlife Refuges Complex recently confirmed a sighting of the reptile in North Key Largo. Originally from South America, these tegus are believed to have established populations in Florida due to escapes or intentional releases from captivity, according to the Florida Fish and Wildlife Conservation Commission (FWC).

Florida is not the only state affected—sightings have also been confirmed in Texas, Alabama, Georgia, and the Carolinas.

A Threat to Native Wildlife

Argentine black and white tegus can grow up to five feet long and are easily recognizable by their distinctive black-and-white banded patterns. They are also strong swimmers, making Florida’s coastal areas and wetlands ideal habitats.

While these reptiles are omnivores, their diet poses a particular risk to native species. They are known to eat the eggs of ground-nesting birds, reptiles, and other small animals. Wildlife officials are especially concerned about their impact on Florida’s sea turtles and gopher tortoises, both of which rely on protected nesting grounds.

Although tegus are not typically aggressive toward humans, they can defend themselves using their tails and sharp teeth if they feel threatened.

Public Urged to Report Sightings

To help manage the spread of this invasive species, the FWC is urging residents to report any tegu sightings. Anyone who spots one of these reptiles is encouraged to call the FWC’s Exotic Species Hotline at 888-483-4681.

As conservationists work to track and control the tegu population, Florida residents are being reminded to stay alert and take action to protect the region’s delicate ecosystem.
