Gila monsters are usually found in the deserts of Southwest U.S. They are venomous and have a powerful bite. Although their venom is akin to that of the coral snake, they are very slow and sluggish and so do not pose much threat to people. It is a good idea to avoid them when possible. Also note that they are protected by state law in Nevada and Arizona. They are also being studied as a potential source of medicine to be used in humans.
