The Lophotrochozoa also include the Nemertea or ribbon worms, the Sipuncula, and several phyla that have a ring of ciliated tentacles around the mouth, called a lophophore.These were traditionally grouped together as the lophophorates but it now appears that the lophophorate group may be paraphyletic,with some closer to the nemerteans and some to the molluscs and annelids.They include the Brachiopoda or lamp shells, which are prominent in the fossil record, the Entoprocta, the Phoronida, and possibly the Bryozoa or moss animals.
