This is the weirdest sea creature we could imagine

The ocean is home to a ton of terrifying animals. The deeper you go, the creepier they get.

A video of the crinoid, also known as the feather star, has gone viral for being horrifically scary and also fascinating.

The beast uses its countless flapping arms to propel itself through the water like a weird, spider-bird crossover, but wait -- it gets weirder.

Crinoids use those feathery arms to feed themselves, and since their stomachs are U-shaped, everything it eats goes straight out its anus, which is next to the mouth.

Gross.

There are tons of variations of the crinoid that come in all shapes, sizes and colors -- check them out if you dare:
