Green iguanas are common reptiles, particularly in regions like Florida and the Caribbean, often seen basking in sunny environments. Their prehistoric appearance often raises questions about their potential to bite humans and pose a danger. This article addresses these concerns and offers information for safe interactions.
The Truth About Iguana Bites
Iguanas can bite humans. While their sharp teeth are primarily for processing plant material, their bites are typically defensive. Their small, diamond-shaped, serrated teeth can cause lacerations and punctures. Bites from wild iguanas are infrequent unless the animal feels threatened or is mishandled.
Reasons for Aggression
Iguanas usually bite when they perceive a threat or are under stress. This can happen if they are cornered, picked up incorrectly, or approached too closely. Male iguanas, in particular, may exhibit territorial behavior and aggression during breeding season, which typically occurs at the end of summer. Accidental bites can also occur if an iguana mistakes fingers for food, especially if they have become accustomed to being hand-fed by humans.
Potential Dangers of an Iguana Bite
An iguana’s bite, while not venomous, can cause significant injury due to their sharp, serrated teeth and strong jaws. These can create deep lacerations and punctures, sometimes leading to embedded tooth fragments within the wound. A primary concern following an iguana bite is the risk of bacterial infection, as iguanas commonly carry Salmonella bacteria in their intestinal tracts, which can be transferred to a wound if the skin is broken. Symptoms of an infection can include redness, swelling, pain, and pus. In rare instances, more severe infections like Mycobacterium marinum have been reported following iguana bites.
Minimizing Risk and Responding to a Bite
Minimizing Risk
To minimize bite risk, avoid provoking or cornering iguanas. Refraining from feeding wild iguanas is also advised, as it can lead them to associate humans with food and reduce their natural wariness. Recognizing warning signs such as head bobbing, tail whipping, or open-mouth displays can help individuals avoid potential conflict.
Responding to a Bite
If a bite occurs, immediate wound care is important. Clean the wound thoroughly with soap and water for several minutes, then apply an antiseptic solution. Covering the wound with a clean bandage helps protect it. Medical attention is recommended for deep wounds, signs of infection, or concerns about tetanus.
