Digging

Giant River Frog (Limnonectes leporinus) - Sabah, Borneo, Malaysia

 

The male would use his powerful hindlegs in order to push the substrate around in the depression and he made quite a sizable one by the time he was done, several body lengths worth atleast. You can see the mosquitos in flight above him but as soon as he stopped digging they would settle back down.
