s. In the breeding season its voice is an inoffensive musical click, rather like a drop of water falling into a pond, but when a large chorus is active, such as in sedge around a dam, the effect is of a loud, continuous rattle. They breed in standing water like most frogs and the adults can swim rapidly and with agility, but they cannot survive if they are unable to leave the water and then they die within a few hours. this seems to be the result of absorbing too much water through their skins rather than simple drowning.
