Full-grown green iguanas are usually between four and six feet, although they have been known to grow up to seven feet long.

Green iguanas, not surprisingly, are green in color, but can be found in many different shade ranging from bright green, to a dull, grayish-green. Their skin is rough, with a set of pointy scales along the iguana's back. Green iguanas have long fingers and claws to help them climb and grasp.
Besides the long fingers and claws mentioned above, green iguanas have many excellent interesting adaptations. Green iguanas have good senses of hearing and smell, and superb vision. Their long tail is also quite sharp, and is snapped in the air as a defense mechanism. The tail can also break off if caught by a predator, but grows back without permanent damage. Green iguana skin is very water resistant, and tough to avoid cuts and scratches. The coloring of the skin helps camoulflage the green iguana, which means that they blend in easily to their surroundings to remain undetected by predators. If they are etected however, and need to escape quickly, these iguanas can dive from trees into water, and swim well. Green iguanas are quite sturdy-- they can fall 40-50 feet to the ground without getting hurt! Male green iguanas have a special flap of skin called the dewlap. Male iguanas can raise their dewlap to appear bigger than they really are, either to intimidate predators, or to impressive females. Both male and female green iguanas can store fat under their jaws and in their necks for times when there is not much food available.
