    Was turning my chaeto over in the refugium and found this thing. It's about 1.5 cm tall and 1cm wide. Egg shaped. It opens its mouth and pulls in water, closes is mouth and constricts it's body forcing the water out. Please see pics.

    Is it mobile or sessile? Overall shape almost looks like a pineapple sponge but the "mouth" looks wrong for that.

    It seems to be stationary. But too soon to tell

    I believe I might have solved it, it had a second ventricle exactly like the one on top but it's located on its side but down a bit. I believe is some sort of sea squirt.

    Oops, has a second ventricle, not had.

    Corella eumyota, or some very close cousin.
