Vertebrates have a segmented vertebral column and brain. Segmentation in biology refers to the division of some animal and plant body plans into a series of repetitive segments. This article focuses on the segmentation of animal body plans, specifically using the examples of the phyla Arthropoda, Chordata, and Annelida.  The gut is separated from the body wall by the body cavity, called the coelom. The segmented compartments of the coelom are usually separated from each other by thin sheets of tissue, called septa, which are perforated by the gut and by blood vessels. The fundamental characteristic of the phylum is the division of the body into a linear series of cylindrical segments, or metameres. Each metamere consists of a section of the body wall and a compartment of the body cavity with its internal organs. By Phil Myers. The annelids include earthworms, polychaete worms, and leeches. All members of the group are to some extent segmented, in other words, made up of segments that are formed by subdivisions that partially transect the body cavity. Segmentation is also called metamerism.  Segmentation. As the lab manual explains, segmentation is the characteristic that the body is divided into repetitive segments arranged on a longitudinal axis. Each segment contains parts of the circulatory, digestive, nervous, and excretory systems. Annelids are among the earliest organisms to appear with a segmented body plan. Other organisms also have a segmented body plan. Arthropods, such as insects, show a strong degree of segmentation with a head thorax and abdomen with specific functions. Echinoderms, such as starfish, are also segmented, but their segmentation is not along a longitudinal axis because of their radial symmetry. The annelids (Annelida, from Latin anellus, little ring), also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches. Annelids are considered members of the Lophotrochozoa, a super-phylum of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans. The basic annelid form consists of multiple segments. Introduction. Annelids are segmented worms. The well developed coelom (fluid filled body cavity) acts as a hydrostatic skeleton with muscles of the body walls acting on it. The body segments of an annelid are partitioned by internal divisions called septa, giving independence of movement to each of them The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body. Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move. There are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli. Annelids are small worms with segmented bodies that have a true coelom that is lined with tissue derived from mesoderm. Annelids are of the three major phyla of protostomes. The name annelidia derives from annellus, which means little ring in Latin. The body of annelids is divided into segments that are separated by septa, and in many annelids, bristles called satae are attached to each segment. Respiration. Aquatic annelids often breathe through gills. Land-dwelling annelids, such as earthworms, take in oxygen and give off carbon dioxide through their moist skin. Annelids are segmented coelomateworms, most of which live in the sea. The annelid body iscomposed of numerous similar segments. Classes of Annelids. The three major classes of annelidsare the polychaetes (marine worms), the oligochaetes(earthworms and related freshwater worms), and thehirudines (leeches).
