Could they be Platyhelminthes?

Just from the look of the creatures, could they be very derived Platyhelminthes? A marine form with a large evertable pharynx might look like that if it was fixed. The Platyhelminthes have a blind-ended multiply-branched digestive system, which is what the pictures instantly reminded me of. Although turbellarians are bilaterally symmetrical, secondary modifications may make the symmetry less apparent, resulting in a small roundish flatworm with a large pharynx, rsembling a "stalk" on a mushroom.
