An iguana has anywhere between 80 to 120 serrated teeth in his jaws. While not all iguanas indicate when they feel threatened, a common sign is the emergence of the dewlap, a flap of skin under his chin that inflates with air to make him look bigger and more intimidating. The pupils of the eyes contract and dilate as the iguana calculates the distance between himself and the threat. When his mouth opens, he is indicating that he is ready to bite. An iguana can move quickly and attack before a human has a chance to react.
