1. Tails That Can Snap Off and Regrow: If a predator grabs an iguana by its tail, the tail can detach so the iguana can run away! Over time, a brand-new tail will slowly grow back in its place.

2. They Sneeze Out Extra Salt: Iguanas have special glands near their noses that filter out excess salt from their bodies. When they sneeze, they blast out a fine salty mist!

3. Green Iguanas Aren't Always Green: Depending on their mood, temperature, health, or age, green iguanas can turn shade of blue, bright orange, pink, or even dark brown to absorb heat better.

4. Some Can Swim in the Ocean: Marine iguanas in the Galápagos Islands are the only lizards in the world that dive underwater to feed on algae, holding their breath for up to 30 minutes.

5. They Use a "Double-Chin" to Talk: Iguanas have a flap of skin under their throats called a dewlap. They extend their dewlap and bob their heads up and down to say hello, warn rivals, or show off.

6. Awesome Olympic Jumpers: Green iguanas spend most of their time high up in rainforest trees. If they sense danger, they can leap up to 40 feet (12 meters) down to the ground or water without getting hurt.

7. Strictly Plant Eaters: Unlike many other reptiles that hunt bugs or small animals, most adult iguanas are herbivores—their favorite foods are leaves, flowers, and fruit.
