Iguanas are reptiles found in the Caribbean, Madagascar, Fiji, The Galapagos Islands and Tonga. Baby iguanas are bright, almost florescent green while adults range from a dark green to brown and black. The iguana's skin is rough and has pointed scales on the back of the neck.
THE GREEN IGUANA or Iguana iguana is a lizard that lives in a tropical rainforest climate and habitat. They are active during daylight hours. Males can grow to 6 feet in length and females can grow to 4 feet Iguanas are found in Central and South America and in countries as far away as Fiji and Papua New Guinea. Their daily life consists of finding a sunny spot to bask in, eating, and avoiding predators.

 Iguana Baby photo by Lisa Crumrine The young iguana are bright green color which helps to camouflage it's body within the bright green leaves of the lower canopy of the rainforest. Quick movements and excellent eyesight help the young iguana avoid capture. As the iguana grows and matures, it loses it's bright green color and becomes a more muted green. |

The
larger iguana prefers a different habitat...the higher, less
dense, less humid environs of the upper canopy. Being "cold-blooded",
the iguana must heat it's body to a high temperature daily.
In the morning, the iguana ventures into the sunlight to take
in the sun's warmth. The sun provides the iguana with another
important service. The heat from the sun helps the iguana digest
it's previously eaten meal. Once heated, the iguana can move
more quickly and spends a good part of the rest of the day
foraging for leaves, tender shoots, and fruit. Later in the
day, the iguana will bask again and perhaps go for a quick
swim in a nearby river, before returning to it's protected
resting spot high in the trees. |
