Summary Introduction
To summarize: The phylogeny of the lophotrochozoans, and cite the adaptive advantages of having a coelom and cephalization.
Concept introduction: The Lophotrochozoa is one of the two major classes of protozoans that include the bilateral animals. They are triploblastic animals and most of them have a true coelom and a tube-within-a-tube body plan.
