Summary Introduction

To describe: The way in which the lifestyle of a gastropod differs from that of a cephalopod.

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. The Lophotrochozoa include the platyhelminthes (flatworms), rotifers, nemerteans, mollusks, annelids, and lophophorate phyla. Mollusks are divided into four clades, namely chitons, gastropods, bivalves, and cephalopods.

Summary Introduction
