Invert ID needed

[Darkxerox]

It's rare that I can't identify something these days, but this little invertebrate is completely stumping me. It appears to have a flatworm or nudibranch style body with two nets it casts out for food that have the shape of a half strand of DNA or a fish ribcage. They're motile and can retract these nets like a vermetid, but have no shell.

Any ideas? I'm not thinking hydroid due to the body shape.

No ideas
But I would pull and “sterilize”

Hydroids are horrible!

I was going to guess jelly like or siphonophorae, but good find.
