A large exotic lizard native to Argentina is beginning to invade Georgia, South Carolina and other southeastern states according to National Geographic.
Biologists say the creatures are omnivorous, eating pretty much anything they can fit in their mouths. They're also extremely hardy, so it's tough to reduce the population or control the spread once the species becomes established in an area.
The black and white Tegu can grow up to be 4 feet long and can reproduce quickly. Tegus have been breeding in Florida for more than a decade, but have only recently begun to spread to other states.
The lizards are described as docile and intelligent, but they will happily eat any smaller animals, fruits, or vegetables they can get to, making them a threat for pet owners and farmers.
