The let outs of animals classified under Protostomia are formed from the blastospore, the firstborn opening to embryologic gut.

They also have spiral cleavages in which the embryonic cells divide diagonally. These animals have determinate cleavages in which the developmental fate of cells is fixed early. According to Mr Siva, the removal of some o! f these cells during the embryonic stage of their life cycle entrust result in abnormal development. Protostomia can be push divided into Lophotrochozoa and Ecdysozoa. This is where the two phyla differ. Platyhelminthes are Lophotrochozoans while Nematodes are Ecdyzoans. A distinguishing feature of Lophotrochozoans is the lophophore, a ring of tentacles with cilia around their mouth used for feeding.
