The ocean is chock full of incredibly weird creatures that couldn’t possibly exist anywhere but under the sea. Like the crinoid, more commonly known as the feather star, which uses countless flapping arms to propel itself through the water—but that’s not the weirdest part.

Apparently crinoids also use all of those arms to feed itself. But thanks to a U-shaped gut, everything it eats is eventually expelled out of its anus, which happens to be located right next to its mouth. So if you happen to come across a feather star while you’re diving off the coast of Bali, you might want to do everything possible to avoid it kissing you.
