Exotic 4-Foot-Long Tegu Lizards Invade Florida

Four-foot-long tegu lizards are invading Florida. Representatives with the state Fish and Wildlife Conservation Commission are concerned, as the invasive reptiles are breeding and thriving in Hillsborough County. Authorities have noted more than 100 confirmed sightings throughout the region.

Wildlife trapper Vernon Yates confirms that around 25 Argentine black and white tegu lizards were trapped and removed in the last two years. However, as they continue to thrive, the population is increasing at an alarming rate. Like many invasive species, the lizards were likely released into the wild by pet owners. Unfortunately, their presence is threatening local wildlife.

Reptiles are often purchased when they are young, small, and very cute. As snakes and lizards grow, certain species become unmanageable due to their size, temperament, and the high cost of food.

TeguTerra.com notes numerous facts to consider when choosing a tegu as a pet. The exotic lizards can live up to 20 years and may exceed 4-foot-long. Primarily carnivores, the lizards require a lot of meat in addition to a variety of fruits and vegetables. Tegu lizards are also “extremely good escape artists,” which can become aggressive.

As they are difficult to manage, large exotic reptiles are quite difficult to re-home, leaving pet owners with few options. Exotic pet owners often release the reptiles into the wild, as they mistakenly believe the solution is the most humane. However, for local wildlife, the invasion can be devastating.

Florida has a specific issue with invasive species, as the environment supports the breeding and lifestyle of many species of reptiles. Non-native reptiles that are currently thriving in Florida include veiled chameleons, Nile monitors, Burmese pythons, boa constrictors, red-eared slider turtles, knight anoles, and iguanas.

As reported by ABC News, tegu lizards are consuming an alarming number of reptile eggs and birds. Biology professor Dr. Deby Cassill said the large lizards nearly wiped out a community of crocodiles in South America, as they ate 80 percent of their unhatched eggs.

Although they are not likely to kill humans or pets, tegu Lizards do bite. Dr. Cassill said “their jaws have some of the greatest force of any lizard jaw” and have to power “to crush the bones of your fingers.” Wildlife officials said Hillsborough residents are urged to store pet food inside to avoid attracting the lizards.

Tegu lizards can reach lengths of up to four feet and have shiny black and white skin. Residents who spot the invasive reptiles can make a report at www.Ivegot1.org or by calling 888-483-4681.
