How to sex a Bufo Toad?

[JordanAng420]

So this is out of pure curiosity...

I love all the cool reptiles we have in South Florida. Sometimes just taking the dogs out for a walk is a "herping expedition" in itself!

I was wondering how to determine the sex in these bufo toads that are all over the place here. I asked my boss, but he told me that I should go look it up. But Mader's book (my bible!) says nothing.

I'm almost positive that toads and frogs don't get "probed" like snakes do. So there must be some sexually dimorphic way to tell. Anyone care to enlighten me?

Males are smaller than females, call, have a dark patch on their throat, and develop nuptial pads on the inside of their thumbs during the breeding season.

 

[ElapidSVT]

males are typically smaller with thicker arms and have nuptial pads on the forelegs to assist in staying mounted on a female during breeding.
