The call of this frog varies from a staccato machine gun sounding burst to a single 'Tok' sound, depending on the call race, which varies geographically.

The male and female frogs can be sexed by the presence of a flap of skin around the thumbs of the females. This is used to froth the water during amplexus to create the floating foamy nest that it lays eggs in, which is roughly the size of a human palm. The tadpoles of this frog are comparatively large (up to 6 cm). This frog spends a minimum of 3 months in the tadpole stage.
