The crustaceans (Crustacea) are a large group of arthropods (55,000 species), usually treated as a subphylum . They include various familiar animals, such as lobsters, crabs, shrimp and barnacles. The majority are aquatic, living in either fresh water or marine environments, but a few groups have adapted to terrestrial life, such as terrestrial crabs, terrestrial hermit crabs and woodlice. The majority are motile, moving about independently, although a few taxa are parasitic and live attached to their hosts (including sea lice, fish lice, whale lice, tongue worms, and Cymothoa exigua), and adult barnacles live a sessile life - they are attached head-first to the substrate and cannot move independently.
The scientific study of crustaceans is known as carcinology. Other names for carcinology are malacostracology, crustaceology and crustalogy, and a scientist who works in carcinology is a carcinologist, crustaceologist or crustalogist.
Structure of crustaceans
Crustaceans have three distinct body parts: head, thorax, and abdomen (or pleon), although the head and thorax may fuse to form a cephalothorax. The head bears two pairs of antennae, one pair of compound eyes and three pairs of mouthparts. The thorax and pleon bear a number of lateral appendages, including the gills, and the tail ends with a telson. Smaller crustaceans respire through their body surface by diffusion , and larger crustaceans respire with gills or, as shown by Birgus latro, with abdominal lungs . Both systems (diffusion and gills) were being used by various crustaceans as early as the Middle Cambrian . More on [ Crustacean ]

Just heard someone use the phrase "ballistic Crustacea" - I think that's a superb band name
