A crustacean is an organism that belongs to the Kingdom Animalia, Phylum Arthropoda, and in the class Crustacea. Examples of the organisms belonging to this class are lobsters, woodlice, krill, shrimp, barnacles, crayfish, and crabs.
It has been said that a barnacle is a shrimp-like crustacean that attaches by the top of itâs head and then kicks food into itâs mouth with itâs feet (Britannica, 1999). This kind of descriptive definition actually distinguishes barnacles from their allies and provides for a fair idea of how the animal operates.
