Some animals learn to use tools to solve problems, for example crows [0]. What if that otter was just using the board to travel longer distances (=> finding more food) by keeping nearby a safer place to rest on?

Otters are known to use tools. I’ve read that some carry around a ‘favorite’ rock under a flap of skin, using it to open shellfish.


This is a slippery slope to a surfing sea otter vs. boat-wrecking orca showdown in the Pacific.
