Sexing by skull shape?

[motiszm]

So I couldn't quite get the angle right, but as you can see these two greens are roughly the same length but have different head shape/size. The one on the left has a much wider head and a longer snout. I've been thinking that the individual on the left is a female, and the one on the right is a male. What do you think?

[GrifTheGreat]

Males usually have what I call the baby face. A Female will have a skull shape that looks like a miniature adult. Females never have the baby face which is a smaller head with rounder contours. Its not 100% like Mike said, but if you see a lot of frogs or you're just that perceptive you can see the differences and be right most of the time. Growth rate is usually a dead give away too. Females grow much faster than males.

I leave the guessing to Jim........I see the difference, but I don't trust that method. It's a good tool to use when trying to buy a frog that is very young, but it is never a 100%, fool proof way of sexing........We have ALWAYS said this. The only way to be 100% sure is to see Nuptual Pads, lack thereof, or to hear the male calling. If you are wanting a specific sex with no room for error, I suggest buying either and older juvenile that is already a sex-able age & size or a young adult. Remember these frogs, with correct husbandry have the potential to live a long life, so purchasing one that is older is not a bad thing provided they have been well taken care of.

So is the only sure-fire way, the pads?

To be 100% sure, Yes.

Okay!

At what size should the pads be out? Or are there late bloomers?

Mine is 2.8" at the moment, and no nuptial pads. No croaking either. Is it a confirmed female then?
