at what age/size will i be able to tell if my rhino iguana is a male or female? im guessing around 2 y/o or 2' am i right, mines is only 8 mo. so i know i cant tell for sure right now, just want to know when to start looking! also are the hemipenis bumps the same as in a green iguana, i mean are they visual from the sides?

On rhinos its really a big differens i head size and the back of the neck gets really swollen at an very early age.. just like the neck of adult breeding MALE green iguanas.. and yes a little bit over two years of age you should be able to see the hemipenis bulges.. it can be hard though sexing young ones if havent seen a lot of young ones to compare with.. my males grow much faster than the females also..at 2y the males are almost 2 times as big as the females.. Or you can just send a pic to TOM C and he can tell you im sure.
Cheers!

some snap shots i got of khaos today!

how old?

he is only 8 mo. so i figured it was to early to tell!

then i would say its a big chance that its a male.. having a large head for its age..90%chance i would think.. or 10%just a bigboned lady

lol one time when i washandling him i was looking at his pores when he pooped but before i got hit in the face with urates(.......ewwwwwwww lol) i thought i saw a little himipenis pop out, but with it all happening so fast who knows! but thanks!

DUDE!!!! haha
good luck with that little dinosaur!

i would say its a male.. not knowing the age.. just on head/body ratio.. the swollen neck and back is possible in females too..
Great looking rhino anyhow in PERFECT HEALTH!!! keep up the good work!

well i notice today that khaos has two "pockets"(for lack of a better word) on each side of his tail, is this the start of hemipenises or am i just seeing things lol i have no idea what im looking for? oh and i got 2 other pics also, i just wanted to share!

right side

left side

khaos-"ummm i think there is something wrong here, do you see it?" i swear i filled that bowl up with greens and veggies this morning at 6 am lol, now its only 4 pm, this is why he poops so much lol!

khaos-"look at my pretty horns, i stab you with them one day, k? now get me noms now!"

Haha he is the cutest thing! i would say that is hemipenis bulges.. thats just a big butt LOL =) the hemipenis in rhinos are almost angular at the underside of the tail and long... in most other iggs they are more round and shorter.. you will know when you see the bulges =P look for pics on adult males on the internet taken from the side.. its really clear..
too soon to see them at this time anyhow!
Funny pics

thanks i figured that just wanted to be 100% or at least 99.9% sure lol!
