Whales: Masters of Deep Ocean Survival

Whales literally collapse their own lungs so they don’t explode underwater. I am deep diving

into marine biology right now and the physics are actually terrifying. To survive the crushing

pressure of the deep ocean, whales have evolved to flatten their ribcages and stop

breathing entirely. They don't store oxygen in their lungs like us because that would cause

barotrauma. Instead, they pack oxygen directly into their muscles using something

called myoglobin, which makes their insides look crazy red. They basically turn

off their metabolism and become oxygen-hoarding torpedoes. It is terrifyingly efficient and I

have never respected a mammal more.
