New Deep Sea Squid
texchanchan writes: "Yahoo reports on a newly discovered species of deep-sea squid, quoting scientists as saying the creatures are very different from normal giant squids. 'New species are a dime a dozen. This is fundamentally different' in behavior and appearance -- with 10 identical long skinny arms and a jellyfish-like hunting strategy. 'We don't know of any cephalopod that has arms like that.' --Michael Vecchione of the U.S. National Marine Fisheries Service. 'I had never seen anything like this creature,' oceanographer William Sager of Texas A&M says."
Here is my reasons
So judging from what I just said, it could be a Hydrozoa family jellyfish or considering the 'wings' a Ctenophora family jellyfish.
That's it. Maybe I'm wrong but those are the first thing that came to my mind when I saw the photo.
Disclaimerthe above is just an assumption based on high school zoology course I took about ten years ago and of course may be incorrect
