14 Utterly Odd Facts About Crinoids, Sea Creatures That Are Basically Aliens

Imagine a 100-foot-long sea flower that can detach itself from its stalk and crawl away. No, it's not a special-effect created for the latest Hollywood sci-fi adventure. This is just your everyday Earth-dwelling crinoid. These ancient ocean creatures resemble beautiful underwater sea lillies in full bloom. But be careful - they're not really flowers. They just look that way as a clever disguise.

What are crinoids? They look like aliens to the untrained human eye. They’re brainless animals that learned how to swim. They’re stomachless life forms that eat constantly, and they grow arms out of their sides five at a time. And they essentially tie everything on Earth together. Mass evolutionary events, dinosaurs, and even church traditions all share connections to these underwater sea creatures.

These amazing facts about crinoids will make you wonder if they were beamed down (or maybe beamed up) into the depths of Earth’s oceans from some other planet entirely.
