GREEN IGUANA

Scientific Name: Iguana iguana
Order
Squamata

Family
Iguanidae

Habitat & Range
The native range of a green iguana extends from southern Mexico to central Brazil, Paraguay, and Bolivia. They are typically found near rivers and other water sources.

Identification
Green iguanas are commonly bright green with blue markings in their juvenile stage but become more drab with maturity. Adults have a fleshy dewlap beneath the throat, which is larger in the males. Dominant males tend to have bright orange forelimbs and pale heads. All Green iguanas have long legs and toes that assist in climbing and running. They can grow up to 6 feet long and can weigh about 11 lbs.

Diet
Although juvenile iguanas eat some insects, adults are herbivores. They primarily feed on leaves, flowers and fruit.

Reproduction & Lifespan
Green iguanas lay eggs seasonally, depending on the amount of rainfall. They often mate in the fall and lay between 20 and 40 eggs in the winter. Incubation lasts about 90 days, resulting in May hatchings.

The average lifespan of a green iguana is 20 years.

Fantastic Fact
A Nod of Approval
Green iguanas use “head bobs” as a form of social interaction. The frequency and number of bobs have particular meanings such as greeting another iguana or courting a potential mate.
