The whale shark spends some of its day cruising through the warm water near the ocean surface. When it’s time to eat, though, it sometimes heads for the fridge — depths of a quarter of a mile or greater, where the water is much colder. That isn’t much of a problem because the shark is a gigantotherm — an organism that relies on its great size and a special anatomy to keep it warm.

Fish often stick together for protection from predators. Staying within a school of fish is usually safer than swimming alone. But it turns out that some fish lend a helping fin when it comes to feeding as well.
