Ecdysozoans shed/molt a tough external coat known as a cuticle as they grow up.
Lophotrochozoa do not shed/molt a cuticle. They can either develop a lophophore (a crown of ciliated tentacles used for feeding), or a trochophore larva (a distinctive larval stage). Some don't develop either of these, and there are other morphological features within the group.
