Ok I FINALLY got off my lazy butt and took some pore pics of Liv Tyler. He/She was measured while sleeping last night at approximately 42 inches STL, so you'd have thought I'd be completely sure by now of the gender. But don't be fooled by his/her size, he/she is only 10 and a half or so months old.
Up until recently, everyone, myself included, was almost absolutely certain the gender was female. Everyone (with any knowledge about iguanas) who saw my ig would automatically say "Wow! What a beautiful girl!", and he/she had not shown any male features at all. This past week, I noticed that the femoral pores were getting bigger all of a sudden, and I now look (hadn't paid attention before) and it even seems to have some brain bumps. There doesn't seem to be much of a bulge there, but the pores seem to get bigger daily. Also no jowls. He/she bobs like a male does, but that I understand is not a determining factor.
This one's a bit of a toughy. Not only is your lizard out of the norms in size/age ratio but the age is not old enough to hit sexual maturity. My vote could go either way for the following reasons: 1st: If those "brain bumps" just started to develop and the pores are suddenly increasing in size, to me this means a possible Tyler. 2nd: There are no bulges at the base of the tail and if the pores to not increase in number (the enlarged ones I mean) I would say you have a Liv. But for human error (as I read in your other posts you were told how old your ig was) we all make mistakes and either over or under- estimate things (some pet stores and places you can purchase an Ig, don't truely know much about Iguanas), so you could have an ig who is older than assumed, and a female.
So...For now, my vote will be female. But, be sure to post updated pics in about 6months. This will give Liv Tyler some time to mature a bit and develop more signs of which side of the track he or she will be staying on!
All the same...I'd say Liv is a very well cared for Iguana and she looks to be in excellent health. Keep up the great work.
Definitely going to test some views here. I, however, am going to say male.
It does look like the brain bumps are developing giving your ig the longer head of a male. The femoral pores are still too small to use them in size comparison, but because of the plugs that seem to be starting to form...SEEM TO BE...again...male. I'm straining my dang eyes trying to see if that's the hint of hemipenal bulges!
