They include various familiar animals, such as lobsters crabs shrimp crayfish 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 , all of which may be referred to as "crustacean lice"), and adult barnacles live a sessile life — they are attached head-first to the substrate and cannot move independently.

Most are aquatic; of these, the majority are marine but some are found in fresh water. Members of the Subphylum include lobsters, crabs, crayfish, shrimp, copepods, barnacles, and several other groups of organisms. All have two pairs of antennae, a pair of mandibles, a pair of compound eyes (usually on stalks), and two pair of maxillae on their heads, followed by a pair of appendages on each body segment (crustacean bodies usually are made up of head, thorax, and abdomen, although the segments composing these tagmata differ among different Classes). The appendages are primitively branched (biramous), and although this condition is modified in many species, adults always have at least some biramous appendages. Crustaceans respire via gills. Like other arthropods, all have a hard but flexible exoskeleton. Most crustaceans are free-living, but some are sessile and a few are even parasitic. Most use their maxillae and mandibles to take in food. The walking legs, including specialized chelipeds, may be used to help capture prey. Some crustaceans filter tiny plankton or even bacteria from the water; others are active predators; while still others scavenge nutrients from detritus.

5. Introduction To The Crustaceamorpha If you aren t yet convinced how important crustaceans are, think about this crustaceamorpha crustaceans have an extremely wide variety of body shapes. http://www.ucmp.berkeley.edu/arthropoda/crustacea/crustaceamorpha.html

Introduction to the Crustaceamorpha Seafood special and other crusties The Crustaceamorpha includes lobsters, crabs, shrimp, pill bugs, krill, barnacles, water fleas, brine shrimp (sea monkeys) copepods ostracods There are many more that remain to be named, particularly in the deep sea. A number of species are economically important to humans as sources of food, and many serve as the main source of food for many fish and whales. If you aren't yet convinced how important crustaceans are, think about this: Crustaceamorpha are the dominant arthropods, and very often the most numerically abundant type of animal in aquatic environments. They make up a significant portion of animal communities in all aquatic habitats, from the most extreme (glacial ice or temporary desert ponds) to the largest (deep ocean) and everywhere in between. The Crustaceamorpha are arguably the most well known of the arthropods because of their contributions to aquatic, aerial, and terrestrial food webs. Crustaceans have an extremely wide variety of body shapes. In fact, body form is so varied throughout the crustacean groups that the only feature all crustaceans share is the possession of two pairs of antennae at some stage of their life cycle. Their colorful exoskeletons and active habits make them favorites to watch at aquariums and when

Unit: Crustacea 1 Introduction CRUSTACEA There are about 42,000 species of Crustacea, including many of the most familiar arthropods such as the crabs, the lobsters and the woodlice. Crustacea is the only group of arthropods that is primarily marine, though there are many fresh water species also. There are some semi-terrestrial species, but these are not, in general, well adapted for life on land. In contrast with other members of the phylum Arthropoda, most notably insects, crustaceans have not been very successful on land. This can be attributed to a number of CONSTRAINTS. However, Crustacea have exploited every habitat of the marine environment, and in so doing have become a very diverse group, from the very large Japanese Spider Crab (look at the specimen in the museum), to the tiny planktonic water flea Daphnia sp. The Crustacea can be divided into six major groups and after a brief introduction to their common body plan, a description of each follows on the remaining unit pages.

As far as I have been able to determine, there is no single, standard glossary that is widely accepted. This is in part because different terms may mean different things for different groups of crustaceans, and in part because many existing glossaries tend to deal with selected subgroups or local faunas rather than with the taxon as a whole. More general glossaries do exist, and include McLaughlin's (1980) book on crustacean morphology and the glossary in the Treatise on Invertebrate Paleontology Moore and McCormick, 1969

Crustacea Ostracoda Crustacea The crustacean body is segmented and organised into distinct regions. The segments, or somites, are typically compressed or depressed to a varying degree, but the dorsal tergum, the ventral sternum and the lateral pleuron are usually recognisable. The body wall is basically chitinous and is most usually reinforced by calcium carbonate to form a rigid exoskeleton. Growth involves periodic moulting of the exoskeleton, involving resorption of calcium salts, and their redeposition in the new-formed outer chitinous skeleton. The body regions comprise a head, thorax (or pereon, mesosome, pereion or peraeon) and abdomen (or pleon or metasome) and an additional tailpiece, the telson. In many taxa a number of the anterior thoracic segments is fused with the head. Although in this case the term head is normally accepted, the name cephalothorax is strictly more correct. In many groups a fold derived from the head extends posteriorly to form a carapace , which covers most or the entire thorax. Primitively, each body segment bears a pair of

A few specimens now housed in the collection were collected in the late 1800's by Stephen A. Forbes. They formed the basis for the first article to appear in the Survey's Bulletin "List of Illinois Crustacea." More specimens were collected during the first half of the 1900's in conjunction with the insect surveys organized by Herbert H. Ross. A large part of the collection comes from specimens collected from 1972 to 1982 for Lawrence M. Page's "The Crayfishes and Shrimps (Decapoda) of Illinois" published in 1985. The collection contains primary types of six species. The collection contains about 83,000 specimens (over 10,000 lots) of approximately 300 species in 26 families. Almost all are from North America. About 50% of the collection is from Illinois; the remainder is mostly from the southeastern United States. The best represented groups are crayfishes, shrimps, scuds, slaters, and pill bugs.
