Florida Lizards: An Overview

Before we start discussing the topic of poisonous lizards, let’s understand first the diverse array of lizards inhabiting Florida.

Types of Lizards Found in Florida

Florida boasts an impressive variety of lizards, each with its unique characteristics. Among the commonly sighted lizards are:

  • Green Anole (Anolis carolinensis): Known for its color-changing ability and vibrant green hue, the green anole is a non-venomous lizard often found climbing trees and shrubs.
  • Eastern Fence Lizard (Sceloporus undulatus): This non-venomous lizard is characterized by its spiky scales and the distinctive dark lines running along its back.
  • Six-Lined Racerunner (Aspidoscelis sexlineatus): Also renowned for its incredible speed, the six-lined racerunner is a non-venomous species frequently spotted darting across open areas.
  • Brown Anole (Anolis sagrei): Another non-venomous lizard, the brown anole, is well-known for its ability to change color, ranging from brown to green.

Venomous Lizards in Florida

While most lizards in Florida are harmless, a few species possess venomous properties. It’s essential to identify these potentially dangerous reptiles to ensure personal safety.

The Eastern Coral Snake (Micrurus fulvius)

The Eastern Coral Snake is one of Florida’s venomous lizards, and it bears a resemblance to the non-venomous Scarlet King Snake, leading to potential confusion. If you found with red and yellow bands touch, it is venomous, and if you dound red and black bands touch, it is kind of non-venomous.

The Gila Monster (Heloderma suspectum)

The Gila Monster is not native to Florida, but it is vital to be aware of its existence due to its venomous bite. It features distinctive black and orange bead-like scales, serving as a warning sign to potential predators.

The Green Anole (Anolis carolinensis)

Although the green anole is generally harmless, it is worth mentioning that it possesses mild venom. However, this venom is not harmful to humans and is primarily used to subdue its insect prey.

Non-Venomous Lizards in Florida

Now that we have explored the venomous lizards let’s shift our focus to the more common non-venomous species that inhabit the region.

The Eastern Fence Lizard (Sceloporus undulatus)

The Eastern Fence Lizard is a docile reptile known for its intriguing territorial displays, often seen performing push-ups on fences or trees.

The Six-Lined Racerunner (Aspidoscelis sexlineatus)

As its name suggests, the Six-Lined Racerunner is swift, agile, and non-venomous. This lizard prefers open sandy areas and can often be seen basking in the sun.

The Brown Anole (Anolis sagrei)

The Brown Anole, though non-venomous, is known for its competitive nature, especially with the native Green Anole, leading to a decline in the Green Anole population.
