Thermal images of penguins and a polar bear reveal how evolution engineered extreme insulation, keeping their bodies warm while barely losing heat in the coldest environments on Earth

He is still pointing that thing at us?
No! Don’t look at him!
So, polar bears and penguins, who dwell in arctic climes, are very cold on the outside. Got it.
Edit: an extra word
Why can’t we make a jacket like that?
Maybe they are really cold all the time, but don’t know how to communicate how 🥶 they are! 😂
Penguins clearly emit more heat but I’ve seen documentaries where penguins gather together as a big crowd. In middle of the crowd it is quite warm.
And spider silk is up to five times stronger than steel in terms of tensile strength, depending upon species and circumstances.
Nature is dope.
So predator is in Antarctica got it
Fun fact: penguin feathers trap air, creating an insulating layer that barely leaks heat.
Somehow, that polar bear still manages to look frightening!
