Crustaceans are a large and diverse group of arthropods, primarily aquatic in nature. They are characterized by having a segmented body, a hard exoskeleton, and jointed appendages. Some well-known crustaceans include crabs, lobsters, shrimps, barnacles, and crayfish. However, the group also encompasses a multitude of lesser-known species that inhabit various habitats around the world.
