Gila Monster runs away from photographer Kevin Toney.

Kevin and Annette Toney went camping this weekend and encountered one of the natives that is named after the Gila Basin, its natural home. The Gila Monster, Heloderma suspectum, a venomous lizard, usually grows up to 20 inches long. The Toneys estimated this one at 15-18 inches, as it scuttled away from then, so it might have been an adult or growing juvenile. 

Although the lizard's bites are venomous, the nerve poison is rarely fatal to humans. The Gila Monster normally preys on small mammals, birds and eggs at night.
