Are There Poisonous Lizards In Arizona?
There is one poisonous lizard you may come across in Arizona, the Gila Monster. This lizard will generally not bite unless it is handled.
They are large lizards with short legs.
They bite using their teeth, they do not have fangs, the venom then enters through the bite.
The Gila Monster will hold onto their victim, whether it's you, your child, or your pet, which makes them very difficult to remove.
The jaws are strong and can cause an injury, which will cause severe swelling.
Symptoms of a Gila Monster bite:
- Burning pain or throbbing in the bite area
- Swelling that gets worse
- Teeth that are stuck in the wound once the lizard is removed
- Nausea or vomiting
- Breathing problems
If you, a family member, or a pet has been bitten by a Gila Monster, seek urgent medical treatment.
