Document Summary
Either a u shaped gut and lophophore (the lophophorate) Had to put them there just because it worked analytically. More than just enteroceolous coelom or schizocoelous coelom. Three coelomic spaces when looking from the side. Colony formed by this one, the asexual budding one. Can extend the pophophores out to make current.

Grabs food with cilia and puts it into mouth, it then goes down. Sessile organism with full digestive track, needs to get rid of waste. Water currents made from lophophore helps push poop away. Usually what happens is a mouth, a sack with the food, the residues out the anus. Called the cecum, absorption and digestion happen here. All there but protocoel is just a small flap. This one has a really little compartment for it in the protocoel. Ovaries nearer to top at lophophore where sperm is travelling.
