An iguana appeared to be paralyzed after temperatures reached the 40s in South Florida on Friday. Video shows the iguana not moving at all in someone's backyard in Miami. Wildlife experts say cold temperatures can send the reptiles into a stunned condition, causing them to lose control of their muscles and even fall from trees. Iguanas are briefly paralyzed until they warm up again. Frozen iguanas should be left alone until they wake up and recover, wildlife authorities say. | CBS News
