One more invasive to deal with in Florida, and this one is dangerous to both humans and wildlife.

A growing population of Nile monitor lizards; massive, aggressive reptiles native to sub-Saharan Africa, has taken hold in parts of the state, and experts say the situation needs to be taken seriously.
These lizards didn’t wander here naturally. They arrived through illegal pet trade, accidental escapes, and intentional releases, and now they’re thriving in Florida’s canals, neighborhoods, and wetlands.
Nile monitors are not your average backyard reptile. Adults can stretch over six feet long, weigh more than 20 pounds, and are strong swimmers and climbers.
They’re fast, defensive, and capable of causing serious injury with sharp teeth, powerful tails, and claws. Even minor contact can be dangerous due to bacteria in their saliva that may lead to severe infections.
State officials are urging residents not to approach or attempt to capture them. Instead, sightings should be reported so professionals can handle removal safely.
Beyond the risk to people, these reptiles pose a major threat to native wildlife. With a strictly carnivorous diet, they prey on vulnerable species including birds, small mammals, and protected animals like gopher tortoises.
The concern is growth. A single female can lay dozens of eggs at a time, and without intervention, populations can expand quickly.
That’s why groups like Florida Fish and Wildlife Conservation Commission stress early reporting and population control.
Florida has learned hard lessons from invasive species before. Officials hope this is one problem that can still be slowed- before it becomes another permanent headline.
