The Physical Description of the Green Iguanas
In a matter of three years, the young twelve-gram green iguana can turn into a one kilogram adult green iguana. Right after they get hatched, their length varies from 17 to up to 25 centimeters. Most of the well-fed matured green iguanas come to weigh at about 4 and 6 kilograms but at times they reach the 8 kilogram weight.
The term green iguana does not stereotype these reptiles. The matured iguanas come in uniform colors whereas the younger ones vary between brown and green. Their colors can also get affected by their health, mood, temperature, and social statures.
One of the distinct features they have is the dewlap that can be found under their throats. The dewlap is much dominant in the male green iguanas rather than in the females. The laterally positioned eyes of the green iguanas are being protected by some immovable eyelids and mobile lower eyelids.
The parietal eye functions as some kind of a meter for the solar energy and contributes much to the maturity of the endocrine and thyroid glands in these reptiles. Lastly, the plates or scales on their heads are much irregular and larger compared to the scales found on the rest of their body parts.
