The decapod ( crustaceans such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon ( abdomen ). [1] [2] Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail:
Body patterns in segmented animals can be independent of any segmental arrangement of the structures over which they extend. However, it is quite common to observe that the segmental framework of a given structure provides the basis for a concordant segmental pattern.
