When the male iguanas mature, their own femoral pores come to develop some outward projections which they tend to use in the copulation strategy to take a grasp of the female iguana.
The skin of the iguana is filled with very minute scales. They are unable to change their skin colors just like the deed of the chameleons but when they get exposed to light, some parts of their skin become darker in color. The young iguanas appear to be colored in pale green alongside with black ringed tails.
As they grow mature, their colors turn out to be more earthly colored which are usually darker especially in their bodies and tails.
Back in their natural habitats, the iguanas appear to be wary since they always feel that danger is beside them. They could always be spotted running and hiding. They make full use of their accurate vision, keen sense of hearing and smell so that they could better ensure their own survival.
They may appear to be clumsy at times but then the iguanas are great swimmers and tree climbers. They usually bask in the morning atop the trees and they can jump into the water anytime they sense danger.
