Pythons and boa constrictors in the wilds of Florida have another reptilian invader in their midst.

The Florida Fish and Wildlife Conservation Commission has confirmed more than 100 sightings of the tegu lizard throughout Hillsborough County, according to ABC's Tampa Bay affiliate WFTS-TV.

The Argentine black and white tegu, Tupinambis merianae, is an invasive species in Florida, and can reach up to four feet in length, according to the fish and wildlife commission.

An average mature female tegu lays around 35 eggs a year, officials said, urging Floridians not to release exotic species into the wild.
