Yes, Phillip is correct. An adult frog breathes in by lowering the floor of
the buccal cavity (i.e. floor of the mouth), drawing air in through the
nares (nostrils) while the mouth is closed, and expels air by raising the
floor of the buccal cavity. There's also some exchange of oxygen & carbon
dioxide across the skin through diffusion.

Diaphragms? Sorry but that is not what is involved. They are an amphibian,
not a mammal! Only mammals have a diaphragm.

If I heard correctly, the crows were making a tiny hole and extracting the
liver. This meant that without the pressure against their diaphragms, the
toads kept on inhaling until rupturing, apparently splattering entrails up
to a metre away. http://en.wikipedia.org/wiki/Exploding_animal#Toads
I've heard of Black Butcherbirds ripping toads open down the length of
their bellies after flipping them over. Hopefully, these pests will be a
welcome major food source for native birds in the future. Cheers,
Tony
