This Blue Iguana’s coloration ranges from a deep blue to a bluish-gray, as suggested by its name. It matures to a length of over 5 feet and a weight of roughly 31 pounds.

This species of lizard has an expected lifetime of between 25 and 40 years and does not reach sexual maturity until between the ages of 4 and 9 years old. They have their young in the spring, usually between the months of April and June.
After mating, the female iguana has the potential to become belligerent and possessive of her territory. The eggs won’t be released from the female until late June or August at the earliest.
She may lay anywhere from 10 to 20 eggs, each of which she will bury one foot underground before tending to for the next 60–90 days until they hatch. There is a significant amount of egg mortality due to the presence of predators.
