Iguana Facts
Drs. Foster & Smith Educational Staff

Iguanas are herbivores, meaning they are plant eaters. Some will occasionally eat mealworms or wax worms.

Although Green Iguanas look slow, they are very quick and move with ease.

Green Iguanas generally live up to 20 years in the correct conditions.

Iguanas are born from eggs, which their mother buries in a burrow until they hatch.

When a female Iguana lays eggs, she can lay anywhere between 10 to 50 eggs depending on the species and age. A group of eggs is called a clutch.

After an Iguana hatches, it is on its own with no help from its mother.

Iguanas are able to hold their breath for up to 30 minutes.

When frightened, Iguanas generally freeze or hide.

Iguanas use their tails as a defensive mechanism, swinging it at a threat which can leave welts on a predator or worse. The Iguana's tail is very powerful and can also be used for swimming.

During mating season, a male Green Iguana may turn orange to attract a mate.

Males have a larger dewlap than females. The dewlap is the fold of skin around the Iguana's throat. They use it to scare predators or attract females.

Iguanas use sunlight to get UVA and UVB light that helps them absorb nutrients correcly to stay healthy.

Green Iguanas have long pointy fingers/claws to help with climbing and holding on to trees, because in their natural habitat they usually can be found 40 to 50 feet above the ground.

Iguanas are diurnal, meaning that they are awake during the day and sleep at night.

Iguanas store fat in the area under their neck for times when there is little to no food.

Although they have eyelids, only an Iguana's bottom eyelid can move.

Iguanas are able to autotomatize, which means they are able to lose part of their tail if needed, and it will grow back in about a year.
