age

Question
how can i tell how old my green iguana is?

Answer
Hi Frank,
Seeing a picture may help me.... there are many things that can affect an iguanas size, making it hard to determine their age.  I;'f they don't have now, or haven't had the proper care, they will be much smaller than they should be at a particular age.  As an example, I had a rescue here that was at least 2 years of age, but was only 7 inches from snout to vent and total length of 17 inches.  At two years of age, they should be no less than 10 inches snout to vent and about 36 inches total length.  As you can see, she had horrible past care.
With male igs, again, given even fair care, will usually show signs that they are indeed male at between 9-12 months of age.  These signs are hemipene bumps at the base of their tail...which is one on each side..and the femoral pores will be pronounced and larger.  These are the pores on the underside of their hind legs.  A males will be more on the order of 0000ooooo and a females more like oooo.....    Are you able to post a picture here..or a link where you can post pictures?  The pics that help the most are:
femoral pores, tail base, and head...of course full body(excluding tail) can help too. Young, well cared for igs have little spikes, are a vibrant green, generally with no belly stripes and may have blue colors on their neck, head and face...as they get older, they get more defined markings on their body and develop  defined stripes on their bellies.
If you would like to have a proper care sheet on the care an ig needs, please let me know.
