    This one stumped me. I tentatively identified the phylum, but I could not tell what it really was without clicking on the link. i will not give it away.

    I actually identified the class correctly just from the mention of “guts”. But I’d never have done so from the picture.

    the link sez

    It creeps forward on its tentacles pretty slowly, at around 2 centimeters per minute, while sweeping detritus-rich sediment into its mouth.

    which I was going to say was wrong, since I thought them to be pelagic, but it turns out that both are true: they are benthic detritus feeders that then swim away!
    Amusingly presented info and vids here.
