How do the differences in the coeloms relate to differences in locomotion? Which characteristics unify the lophophorates?

How is the coelom used to differentiate among these different types of worms? Platyhelminthes exhibit a coelom only in the embryo, Annelids exhibit a coelom only in juveniles, and Nematodes exhibit a coelom in both embryos and adults. Platyhelminthes exhibit a coelom in embryos, Annelids exhibit a coelom only in juveniles and Nematodes lack a coelom. Platyhelminthes develop a coelom before the anal and oral pores develop, Annelids develop a coelom at the same time the anal and oral pores develop, and Nematodes lack a coelom. Platyhelminthes develop one coelom, Annelids develop two coelom, and Nematodes develop three coelom but then lose the one derived from mesoderm. Platyhelminthes lack a coelom, Annelids exhibit a coelom and Nematodes have a pseudocoelom.arrow_forward
