Need help with sexing Colorado River toads

[John]

Size (females are bigger) and body shape (females are wider) are the main methods. I can usually tell just by looking at them. Do you have any photos?

if they are still sub adults it is unlikely that they will be sexable, otherwise what John said, it is the same with the majority of toad species.

Actually I can sex the juveniles pretty well from about an inch and a half in size - males just have a different appetite and shape to females.

That photo is pretty small. Do you have more, bigger photos. And can you tell us how long they are (from tip of nose to the tip of their vent/rear end)?
