75% of all living species belong to this phylum! It includes diverse groups such as insects and crustaceans. All arthropods have 3 body segments: head, thorax, and abdomen. These animals have a hard exoskeleton that is secreted from the epidermis (skin). Advantages of exoskeletons are that they are waterproof, and prevent dehydration and are good structures for protection from predators. The major component of the exoskeleton is a polysaccharide called chiton. When an arthropod grows, the exoskeleton must be molted External structure of a crab. and a new one is formed. Most marine arthropods belong to the Class Crustacea. Some examples of crustaceans are crab, lobster, shrimp and small planktonic creatures such as copepods and euphausids (krill). The head and thorax are fused in crustaceans, forming a single structure called a cephalothorax. The main body shell of the crustacean is called the carapace. They have 5 walking legs (periopods) and two pinchers (chelae). Crustaceans also have 2 sets of antennae and stalked eyes. One crustacean that was once believed to be a mollusc is the barnacle! Barnacles are only found in the marine environment and they are sedentary (do not move). Barnacle larvae settle on their heads and stick their feet in the air to feed! They were confused with molluscs because of their calcium carbonate shell. SUBCLASS MALACOSTRATA Hemigrapsus oregonensis (Yellow/Green Shore Crab) Description: Grey/green in colour. Juveniles are mottled.

Hexapoda image from Tree of Life Salticidae The arthropods constitute the most successful and diverse form of life on Earth, constituting millions of species in a diverse range of habitats, and varying in size from microscopic to quite large. The name "arthropod" comes from the Greek, arthros jointed, and podes , feet. Hence, jointed feet. All arthropods possess a jointed rigid exoskeleton, which both supports the musculature and protects the animal. The exoskeleton is formed by the cuticle, a protective layer composed mostly of chitin, long chained molecules of the sugar acetyl glucosamine, which when cross-linked form tough fibers embedded in a protein matrix As the animal grows it has to shed its exoskeleton at regular intervals, a process known as

Peripatus Home Page Biology Taxa Updated: 10 Feb 2003 Arthropoda Abstract This page presents a brief systematic overview of the Arthropoda, from their origins to the present. Keywords: Arthropoda, arthropod, Ecdysozoa, Tactopoda, Onychophora, Euarthropoda, Tardigrada, Arachnomorpha, Trilobita, Chelicerata, Crustacea, Mandibulata, Atelocerata, Hexapoda, segmentation, ecdysis Introduction Arthropods are bilaterally symmetrical segmented animals with paired and usually jointed appendages on some or all of the body segments. The body is surrounded by a tough organic or organic-mineral cuticle which functions as an exoskeleton. In order to grow, arthropods must molt their exoskeleton. At least half of the described species of living animals are arthropods (mostly insects), but arthropods are less common as fossils. The most familiar group of fossil arthropods is undoubtedly the trilobites. Fossil groups have been incorporated into arthropod classification systems at least since the 18th century, but important new finds - especially of very early stem group organisms, such as those of the

Last, fourth head limb designed as the trunk limbs having a short exopod but well-developed endopod with peculiar, banana-like outgrouwths laterally. No proximal endite as in stemgroup crustaceans, but position of 2nd limb at least paroral and posteromedially directed as in crustaceans. Reconstruction of larval stages and morphology Stages include the pattern of pores on the tergum. Cross section shows the orientation of limbs when the body is artificially streched.

Phylum Arthropoda Metamerism as the result of teloblastic growth. Tendency towards regional body specialization. Chitinous cuticle forming exoskeleton with sclerites (tergites, pleurites, and sternites). Growth by ecdysis. Each body segment primitively with 1 pair of jointed appendages. Generally 1 pair of lateral, compound eyes, and one to several median eyes. Scizocoelom reduced to portions of excretory and reproductive systems. Main body cavity an open hemocoel. Dorsal heart with lateral ostia. Complete gut. Nervous system comparable to annelids. Striated muscle arranged in segmental bands. Most gonochoristic. Direct, indirect, and mixed development. Subphylum Chelicerata Body divided into cephalothorax (prosoma) and abdomen (opisthosoma). Antennae absent. Generally 8 pairs of appendages. First pair of appendages modified as chelicerae. Second pair of appendages modified as pedipalps. Class Merostomata 5 or 6 pairs of abdominal appendages modified as gills. Posterior telson. Limulus polyphemus - horseshoe crab [juvenile] [adult] Class Arachnida Unsegmented prosoma generally covered dorsally by a solid carapace. Waxy epicuticle. Book lungs and tracheae.
