Iguanas have a life span of about 15-20 years in captivity. Green iguanas are a threatened species due to loss of habitat. Green Iguanas live in rainforests, usually near river banks. Green Iguanas vary in color from green to brown. 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. They eat leaves, flowers, and fruit. They also supplement their diet with insects and other small animals. 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.
