The Horseshoe Crab Saved Millions of Lives

This is the horseshoe crab. Believe it or not, it might have just saved your life. They’ve been roaming the oceans for over 450 million years. These aren’t actually crabs. They’re more closely related to spiders and scorpions, which explains those creepy crawly legs. These armored aliens are picky eaters. They use their feeding arms to turn over clams and worms for a tasty snack. But that’s not all these ancient astronauts are good for. Their blood holds a secret weapon. Unlike other animals, their blood is bright blue. This blue blood contains a unique compound called limulate. Limulate has an incredible ability to detect even tiny traces of bacterial contamination. Thanks to these ancient aliens, countless lives have been saved from deadly infections. #shorts #horseshoecrab #crab #animal #animals #animalfacts #animalshorts #animaldocumentary #nature #wildlife #wildlifewonders #animalsvideo #wild #oceancreatures #seacreatures
