Hi all
I have a group of Anaxyrus/Bufo cognatus and am quite stumped as to sexing them. four of them are between 6.5 and 7.5cm long, one is smaller at about 5.5cm. They have recently warmed up from around 15 to 20C and have become more active. The small animal has taken to making odd chuckling calls and chasing after others trying to amplex them, so I assume that one is a male. One of the larger 4 looks like it has an extra baggy throat, although it has never called, and I suspect that that is a vocal sack.However, the other three have left me clueless! What is the best thing to look for to sex them? How large are females usually (I can find only records of maximum sizes, which is not helpful)?
Any help would be appreciated
