   Extractions: A nyone who has been to the beach has probably seen starfish or sand dollars. The more intrepid beachcomber may find brittle stars sea cucumbers , or sea urchins. These and many other organisms, living and extinct, make up the Echinodermata, the largest phylum to lack any freshwater or land representatives. Most living echinoderms, like this sand dollar from Baja California, are pentameral ; that is, they have fivefold symmetry, with rays or arms in fives or multiples of five. However, a number of fossil echinoderms were not pentameral at all, and some had downright bizarre shapes. Echinoderms have a system of internal water-filled canals, which in many echinoderms form suckered "tube feet", with which the animal may move or grip objects.

   Extractions: Echinoderms have been compared to living, moving castles. Castles are made of interlocking blocks, with a single main entrance and numerous slit windows for air and for defense. Echinoderm skeletons are made up of interlocking calcium carbonate plates and spines. This skeleton is enclosed by the epidermis and is thus an endoskeleton. In some, such as sea urchins, the plates fit together tightly. In others, such as starfish, the plates are more loosely bound, and in sea cucumbers the plates are usually microscopic. But whatever their shape, the plates of echinoderms have a very typical microstructure: electron microscopy reveals them to be, not solid blocks, but fine networks of calcium carbonate forming a structure known as stereom . Each skeletal element of an echinoderm is actually a single crystal of calcium carbonate, very finely branched and structured.

   Extractions: Unit: Echinodermata 1 Introduction The Echinodermata, (from the Greek meaning spiny skin), is a phylum containing about 6000 species, and constitutes the only major group of deuterostome* invertebrates. Since most echinoderms possess some form of calcareous* skeleton, we have a very good fossil record of the evolution of this group, although many aspects of their evolution are far from clear. Their relationship to other phyla is also poorly understood, for the echinoderms were already well differentiated at the onset of the Palaeozoic* era, and their distinctive characteristics seem to be unparalleled in any other group. The echinoderms are a large and successful, entirely marine group of coelomate* animals. They are mainly free-living, but fossil evidence indicates that they are derived from sessile* ancestors and they have shown two mutually opposing trends. The first trend has been towards a free-living habit, with the development of jaws and oral appendages for seeking out food. The second, more primitive trend, has been to adopt a sessile habit and become attached to the substratum by the aboral* surface or stalk. The crinoids (

Top End 5 pages with 110 photos of echinoderms (Echinodermata) There are 5 related classes in the phylum Echinodermata (the Latin name means "spiny-skinned"): Echinoderms are characterized by radial symmetry, several arms (5 or more) radiating from a central body (= pentamerous). The body actually consists of five equal segments, each containing a duplicate set of various internal organs. They have no heart, brain, nor eyes. Their mouth is situated on the underside and their anus on top (except feather stars, sea cucumbers and some urchins). Echinoderms have tentacle-like structures called tube feet with suction pads situated at their extremities. These tube feet are hydraulically controlled by a remarkable vascular system. This system supplies water through canals of small muscular tubes to the tube feet (= ambulacral feet). As the tube feet press against a moving object, water is withdrawn from them, resulting in a suction effect. When water returns to the canals, suction is released. The resulting locomotion is generally very slow.

    Extractions: Ophiuroids are a large group (over 1600 species) of echinoderms that includes the brittle stars (Ophiurida) and basket stars (Euryalida). The more familiar Ophiurida, or brittle stars, usually have five arms and superficially resemble true starfish (Asteroidea). However, brittle stars have long, flexible arms (hence the other common name for ophiuroids, "snake stars" and a central, armored, disk-shaped body that is clearly demarcated from the arms. Instead of crawling on hundreds of tube feet like starfish, brittle stars move fairly rapidly by wriggling their arms. These agile arms are supported by an internal skeleton of calcium carbonate plates that superficially look like vertebrae, and that are in fact called vertebral ossicles . These are moved by a system of muscles and linked together by ball-and-socket joints. The body and arms are also protected by calcium carbonate plates, and the arms generally bear delicate spines. Basket stars (Euryalida) have a similar structure to brittle stars, although they are usually larger. However, their arms are very highly forked and branched, and even more flexible than those of brittle stars. Ophiuroids can be found in most parts of the world, from the Arctic and Antarctic to the tropics. Ophiuroids are common in many shallow-water marine habitats, and include a few species which can adapt to brackish water, which is quite unusual for echinoderms. Ophiuroids are dominant in many parts of the deep sea, where in certain regions the bottom may swarm with brittle starts. Basket stars also tend to live in deeper water. Most ophiuroids are scavengers and detritus feeders, although they also prey on small live animals such as small crustaceans and worms. Some, in particular the basket stars, filter-feed on plankton with their arms.

General agreement has yet to be reached on many points of echinoderm classification, as may be seen from the alternative classification to be found in different textbooks. However, most workers divide the living echinoderms into four classes;
