Pictures of iguanas (species Iguana iguana), found from Southern Mexico through Central and South America.
They are normally found in the rainforest canopy near rivers and streams. They enjoy basking in the sun which is important for increasing body temperature (they are cold blooded) and aiding digestion. Both sexes have a dewlap (found below the lower jaw) that also aid in temperature regulation. Juveniles are omnivorous (they eat both plants and animals) feeding mainly on leafy greens and some insects, eggs, or smaller vertebrates while adults are mainly vegetarian and eat flowers, fruits, and leaves. They can grow up to 6 feet long and weigh up to 8 pounds. Females are generally smaller than males. Their tail can auto-amputate as a defese in escaping predators.
