Iguana
The green iguanas of Central and South America aren't exactly lazy, but they do spend most of the day just hanging out. These large, seven-foot reptiles can be found way up in the treetops in the rain forest canopy, basking and foraging for flowers, fruits and leaves.
Because their gray-green skin and scales blend so well into the foliage, iguanas are hard for predators to spot. But when they do feel threatened, these lean green machines dive into action, dropping up to 50 feet into the river below. From there, they use their long tails to propel them through the water.
Should a predator be lucky (and fast!) enough to catch an iguana's tail, the lizard employs one last line of defense. He is able to release his tail and run or swim to safety as it breaks off. But that's not the end of this tale--or his tail, which eventually grows back without permanent damage. br>
