The average cost of rehabilitating a seal after the Exxon Valdez oil spill in Alaska was $80,000. At a special ceremony, two of these most expensively saved animals were released back into the wild amid cheers and applause from onlookers. A minute later, what happened?

The seals were eaten by a killer whale

To the shock of those watching, that's exactly what happened. A $160,000 meal for that whale!
