Crustaceans are equipped with jointed appendages and a hard external skeleton (exoskeleton) which we often call the shell. The shell is usually jointed. Most soft body parts are contained within the shell. The bodies of crustaceans display bilateral symmetry, meaning that the body is organized fore and aft.Crustaceans have a definite brain in the head at the front of the body.arnacles develop from an egg into a larval stage in a manner similar to lobsters, shrimps and crabs. Barnacles also possess the jointed appendages found in other crustaceans. But barnacles only display some of these characteristics as larvae.
