10 Lizard Species Found in Florida

Large & Invasive Species

Florida is home to a variety of lizards, including several species that are considered invasive. Invasive lizards are those that have been introduced to an area by humans and which pose a threat to the local ecosystem.

These lizards can be harmful to humans, as they can compete with native species for food and habitat. In addition, they can transmit disease to native wildlife and humans.

Some of the most common invasive lizards in Florida include the green iguana, brown Anole, and house gecko. These lizards can grow to be quite large, and their populations can quickly grow out of control.

If you see one of these lizards in your yard, it’s best to report it to the authorities so that it can be removed before it does any damage.

Male anoles have a pink dewlap on their necks, which turns red when they are ready to mate or fight. The anole is a ubiquitous lizard, and in the summer months it can often be seen basking in gardens and yards.

What’s the most common lizard in Florida?

Can Florida lizards hurt you?

Venomous animals are typically defined as those that have a venom gland connected to hollow fangs that they use to inject their poison into their prey.

However, there are no known lizards in Florida that fit this definition. There are, however, several species of lizards in the state that do contain poisonous saliva.

These lizards can spread their toxins through bites or through contact with their skin. While the effects of these lizards’ toxins are usually not serious, they can cause discomfort and pain.

As a result, it is best to avoid handling these lizards if possible. If you must handle one of these lizards, be sure to wash your hands thoroughly afterward.
