It's squidworm!

And it's really bizarre. Teuthidodrilus samae is one of the weirdest looking things on the planet, a marine worm 9cm long with two armlike appendages used for feeding, eight qrmlinke appendages used for breathing (yes, breathing), pink paddlelike appendages for propulsion, and, last but not least, a dozen frondlike sensory organs. You have to take a look at the image: words can't do it justice.
