I want to know the answer to the following question:
What are the phyla that have a ring of ciliated tentacles around the mouth called?
All the background I'm provided with is that "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.". Is that enough to answer the question?
