Eli5: How are humpback whales able to survive in both tropical temperatures and antarctic ones (when my fat can’t protect from either)?
In: 58
In cold water, the blubber insulates them.
in warm water, they actually struggle not to overheat. They have a cooling system built into the roof of their mouth. It’s basically a structure that they can pump blood through to cool it, by gulping cold ocean water. Its like the radiator on a car.
