Survival Through Adaptation

Some animals, like bats and hummingbirds, can literally switch between being warm-blooded and cold-blooded.

When they're active, they generate their own body heat. But to save massive amounts of energy

while resting, they let their body temperature drop to match their surroundings. It's an incredible

survival hack. This adaptation isn't unique. Marine iguanas sneeze out excess salt

to survive in the ocean. Desert plants have tiny or waxy leaves to prevent water

loss. Every living thing has these amazing, built-in strategies to interact with

the non-living world, proving that survival is all about adaptation.
