Many predators inhabit a territory packed with prey, but here there’s nothing like that for them. Each may travel for miles, night after night, prepared to eat anything it can find, dead or alive. The shoreline is a good place to search. There might be some small creatures to catch here, or maybe something that the tide has brought in. The carcass of a wallaby has been washed ashore. Tasmanian devils can eat 40% of their bodyweight in one session and they have hugely powerful jaws. They tackle everything, even bones. Back at the den, there are other hungry mouths.
