I know its said that there is no sexual dimorphism in leucomelas. My juveniles are ~7 months OOTW and I'm seeing a difference in toe pads. Maybe its just that one is older than the other, or individual variation, but it seems pretty clear there is a difference. I noticed these two next to each other and started thinking about their differences. I notice a difference in head structure and toe pad size. Its really hard to get a look at, but Im trying to see if there is any tympanum dimorphism (anyone chime in here?). I'm not looking for advice or being impatient, rather just making notes to see if anything could help give a better guess for probable sexes. Everything about these frogs fascinates me, and I'm into noting everything down. Anyone else obsess about physical traits? Its very cool, and since I'm new, keeping track of everything will help me down the road I'm sure. I use the advanced search function a lot, but I can't seem to find things, lol.
