Iguanas are lizards identified by their stocky stature, the saggy skin on their throats and therefore the spines that protrude from their heads, necks, backs and tails. Iguanas are popular pets and may live 15 to twenty years if cared for correctly .
Iguanas are available a variety of colours , from nearly yellow, to bright green, to grey. Some have hints of red or orange on their spines, legs, and other appendages. Younger individuals tend to be a brighter shade of green, while older individuals fade into yellow, grey, or a mix of both.
