We humans can rely on our internal body heat to help keep us warm. But what can cold-blooded animals do when faced with the threat of freezing? Here are three creatures that have come up with some...“cool” solutions. Hosted by: Michael Aranda SciShow has a spinoff podcast! It's called SciShow Tangents.

When you think about coral reefs, you probably imagine a sparkling tropical oasis that you can easily see while snorkeling or diving, but reefs can be found as deep as 8000 meters! As deep as they are, those reefs are still not immune to the effects of human activities, nor are we outside their sphere of influence.

Thanks again to the Monterey Bay Aquarium for partnering with us on this episode of SciShow. The Aquarium’s mission is to inspire conservation of the ocean. So give them a follow on their social media accounts or visit their website at http://montereybayaquarium.org. If you’re able to, please consider making a donation to help the Aquarium continue their mission while they’re closed. Your gift will be put to work immediately for ongoing animal care and maintenance of the Aquarium: https://mbayaq.co/2zbN5GX Pelagic red crabs are actually lobsters - and that’s not even the weirdest thing about them! They sometimes wash up on shore in droves, signaling large scale climate events like El Niños and serving as a warning to marine biologists of our changing climate.
