Scientific name: Ctenosaura similis

Known as the fastest lizards in the world, running at 34 kilometers per hour, these dinosaur-like iguanas are terrestrial in nature but are also capable of skillfully climbing up trees and other high places if needed. Capable of growing to 3 to 4 feet, the spiny-tailed iguana gets its name from the sharp, barb-like spines found on its powerful tail used to ward of predators.
Although generally dark gray, or black and white as adults, hatchlings start off as bright green and gradually lose their color as time goes by. As juveniles, they tend to be insectivorous, feeding on worms and bugs, but later become pure herbivores, devouring flowers and fruits.
