Basking sharks have essentially no natural predators.
They are known to be attacked by orcas, but few predators hunt these sharks. There is some information that great white sharks feed on the carcasses of basking sharks.
Tasmanian devils prefer burrows as shelter. They most often use those left by wombats.
Each individual has several burrows that it uses. They also pass from generation to generation so that one burrow can provide shelter for dozens of generations of devils over hundreds of years.
