I’m starting to suspect that Stew might be a girl. I’m not sure, because he/she hasn’t laid eggs or displayed any male genitalia. But he/she doesn’t have the secondary sex characteristics distinctive to male iguanas.
Stew doesn’t have fatty bumps behind the eyes, or enlarged jowls or large, rounded subtympanic shields (you totally want to know what that is, don’t you?), or protruding femoral pores.
It’s so obvious, I’m almost embarrassed I ever believed Stew was a boy.
Question is, if Stew is a girl, do I continue to call her Stew (short for Stewardess, perhaps) or change her name to Stella? Or Irene.
