Green Iguanas are a type of lizard. They are also called common iguanas. These reptiles have a long tail, eyelids, and four sprawling legs. Iguanas have a life span of about 15-20 years in captivity. Green iguanas are a threatened species due to loss of habitat.

Habitat: Green Iguanas live in rainforests, usually near river banks. They are found in Central and South America, some Pacific islands, and the Florida Keys (USA).

Anatomy: Green Iguanas vary in color from green to brown. They usually weigh about 10-15 pounds (4.5-6.8 kg) but can weigh up to 40 pounds (18 kg). They can grow to be up to 6 or 7 feet (1.8 to 2.1 m) long. Green Iguanas have a serrated crest along their back and a large dewlap hanging from their chin. Males have large scales under the ear. They use their powerful legs to swim and climb trees.

Diet: Iguanas are primarily herbivores (plant-eaters). They eat leaves, flowers, and fruit. They also supplement their diet with insects and other small animals.

Reproduction: A female will dig a shallow trench in moist soil near a riverbank in which she will lay 30-40 eggs. After covering the eggs with soil, there is no more parental care. When the eggs hatch, the young live in trees and eat insects that they catch themselves.

Predators: Iguanas are killed by some large birds of prey, foxes, rats, weasels, some snakes, and people. Their eggs are also eaten by many animals.
