Florida’s warm, humid climate provides a suitable environment for a diverse array of lizard species, both native and introduced. Many residents and visitors often wonder about the biting tendencies of these common reptiles. Understanding their behavior, particularly concerning bites, helps in safe coexistence.
Understanding Lizard Bites in Florida
Lizards in Florida can bite, though incidents are uncommon and typically occur as a defensive response. The severity of a lizard bite largely correlates with the animal’s size. Smaller species inflict minor bites, often more startling than dangerous.
None of the common lizard species found in Florida are venomous. Venomous animals inject toxins through a bite or sting, unlike poisonous ones which are toxic if eaten or touched. While some lizards globally are venomous, these species are not found in Florida. However, any animal bite carries a risk of bacterial infection, as lizard mouths can harbor various bacteria.
Common Florida Lizards and Their Biting Tendencies
Among the most frequently encountered lizards in Florida are anoles, including the native green anole and introduced brown anole. These small lizards typically display aggression toward other anoles, especially males defending territory. While they can bite if threatened or handled, their bite force is weak and rarely breaks the skin.
Another common group is geckos, with invasive species like the Tokay gecko known for strong bites and a tendency to clamp down, which can lead to bacterial infections. Other gecko species generally have very weak bites. Skinks, often observed moving quickly through gardens, are generally harmless and pose little threat of biting.
Larger, non-native species like iguanas and tegus present a different level of concern. Green iguanas, common in South Florida, possess sharp, serrated teeth and powerful jaws capable of inflicting painful bites. They also have strong claws and tails used defensively. Iguanas are typically not aggressive towards humans unless provoked or cornered.
Tegus, particularly the Argentine black and white tegu, are another invasive species established in Florida. These large lizards have powerful jaws and a significant bite force, capable of crushing bones. They are generally not aggressive unless threatened or handled, and are more likely to flee than to attack. Nile monitors, also invasive, pose a risk of serious bites due to their size.
Safety and Prevention When Encountering Lizards
To ensure safety when encountering lizards, observe them from a distance. Attempting to catch or handle any lizard, especially larger ones, can provoke a defensive bite. If a lizard does bite, do not pull away forcefully, as this can worsen the wound or injure the lizard.
Should a bite occur, first aid involves cleaning the wound thoroughly with soap and water. Apply an antiseptic to help prevent infection. Monitor the wound for signs of infection, such as increasing redness, swelling, or pus. Seek medical attention if the bite is deep, from a larger lizard, or if any signs of infection develop. Ensure your tetanus vaccination is up to date.
