Gila Monster (Heloderma suspectum)
Gila Monsters are one of only two venomous lizards in the world! They produce venom in glands of the lower jaw and channel it along grooves in the teeth for secretion. Once a Gila monster bites, it generally holds on tight, chewing more and more venom into the bite. The venom is believed to be a defensive weapon as most of the lizard’s prey is defenseless.
Gila monsters are most active during daylight from spring through fall, but they spend up to 98 % of their time in their burrows. When they are above ground, they tend to move rather slowly and will first try to escape if a predator comes near. They will also hiss and open their mouths very wide (this behavior is called gaping), showing off their pointy teeth. They bite only as a last resort. The bite is extremely painful to humans but rarely fatal. Most human bites occur when someone purposely aggravates or tries to handle a Gila monster. If left alone, they are harmless.
