Need help with sexing Colorado River toads

[John]

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.

Sure,here is the link http://www.flickr.com/photos/47785392@N05/4535824719/

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)?

They are both 4"

Looks like 2 males to me, though the second one might be female. Check the thumbs of the front feet - do they have "pads" there? Males have these to hold on to females during breeding.
