Echinoderms Phylum Echinodermata Echinoderms have a few important aspects in common. They have bony ossicles in their body. They have a water-vascular system which pumps water through the madroporite . They also have small jaws that are supported by the water-vascular system. And they have tube feet which they use to attach to objects, for protection, as well as to obtain food. They have radial symmetry and most can regenerate lost limbs. The following classes are types of echinoderms: Class Asteroidea Starfish or Sea Stars (Six-rayed Starfish Leptasterias hexactis )sea stars have fairly developed senses of smell, touch, and taste. They also can respond to the presence of light. They normally eat small prey whole, but they have to extrude their stomachs to digest larger prey outside their bodies. Sometimes, sea stars will use their tube feet to help pry open bivalves, and then they will slip their stomachs in between the two shells. Class Ophiuroidea Brittle Stars (Daisy Brittle Star Ophiopholis aculeata Another picture of a Brittle Star (*) found in all oceans (but mainly in the tropics). The group includes about 2000 species, varying in color. They eat decaying matter and microscopic organisms that are found on soft muddy bottoms.

Echinodermata: "The nervous system of starfish consists, first od a central nerve ring around the mouth, and second, of peripheral nerves radiating from this ring and into each of the arms. If laid on its back, a starfish can soon right itself... by little muscular feet..., and do a somersault. But not all arms function at once." - Jacques Loeb, Experiments on Echinoderms, 1900 The elegant Feather-Star specimen, anative of the Mediterranean, has a permeable membrane by which the interal fludis are extruded into the sea.

Credits Introduction The echinoderms (or "spiny skins") are a diverse group of completely marine animals. They are known from the Cambrian to the Recent and are found in shallow marine waters as well as the deep abyssal plains. They have a soft body encased in a hard rigid shell or exoskeleton (called a test ) made of individual plates (or ossicles ) made up of numerous thin plates. Many echinoderms have spines covering their test (e.g. the sea urchin). This group includes such familiar sea-shore creatures as starfish and sea urchins, as well as a number of less known types, and a whole range of paleozoic forms that are no longer around. There are some 6000 recent species, distributed among five classes. But these are only a small fraction of the number and diversity of types that lived in past ages, especially during the Paleozoic era when the group was at its height.

Echinoderms One of the most familiar groups of marine invertebrates. All are marine and most are shallow bottom dwellers, characterized by a striking five membered radial symmetry. The parts of the body are radially arranged around a central region in which the mouth is located. All have an internal calcareous skeleton that normally bears projecting spines or tubercles that five the body surface a warty or spiny appearance. Hence, the name "echinoderm" is derived from two words, "echino" (spiny) and "derm" (skin) or "spiny skin." (Brittle Star Album) The name of this class is derived from words meaning "serpent tail like" and is applied to serpent stars and brittle stars because of their long, slender, snake like arms. In brittle stars the arms break very easily if handled or disturbed. The digestive and reproductive organs are limited to the central disk and do not extend into the arms as they do in the seastar. One opening in the center of the lover surface serves as both the oral and anal opening. (Feather Star Album) (Sea Cucumber Album) (Sea Urchin Album) All are armed with movable spines that vary from very short to more than 30 centimeters in length. Some are sharp and mildly toxic, presenting a hazard if they break one's skin. As in seastars, the mouth of the sea urchin is located on its underside and the anus on the upper side. Exceptions are the heart urchins and sand dollars in which both the mouth and the anus are on the underside. The principal enemies of the echinoids are seastars and people. Sea urchin eggs are eaten by people and because the quantity of meat (gonads) per sea urchin is small, many urchins are collected to comprise a meal. Most sea urchins tend to e less conspicuous during the day than at night. Most take cover under a coral head or rock outcropping while some have devised interesting methods of hiding during the day.

Phylum Echinodermata Species Home Introduced Species When on a foreshore forage, you will undoubtedly find some echinoderms. These include: Seastars (Classes Crinoidea Asteroidea Ophiuroidea Sea Urchins (Class Echinoidea) ... Sea Cucumbers (Class Holothuroidea) There are many different types of each found at the Marine Discovery Centre. The characteristic which groups these animals together is the internal calcareous skeleton. Most have a body plan based on five or multiples of five, with five arms, five rows of tube feet (small legs with suckers used for movement, food capture, adhesion and respiration), five pairs of gonads etc. They lack a head but have a mouth region, usually on the lower surface. A unique feature of this group is the water vascular system, involving features such as a circular canal, madreporite (external opening) and tube feet. Echinoderms also have the amazing ability of regeneration, capable of regrowing broken off arms. Some species can also grow into new individuals from just an arm that is released (asexual reproduction). A few exceptional species, such as the vulnerable species Patiriella vivipara found locally, bear live young.

Kingdom Animalia PHYLUM ECHINODERMATA INTRODUCTION Most zoologists believe that this group of animals arose from bilaterally symmetrical ancestors even though the animals show a pentaradial symmetry . Many of them have a bilateral larval stage and hence the radial feature may be secondarily acquired. Further, they are definitely triploblastic and eucoelomate . Echinoderms are marine animals and include sea stars, sea urchins, sea cucumbers, and sea lilies. The body parts are arranged in "fives" around the oral/aboral axis. Radial symmetry is an adaptation to sedentary life-styles. Echinoderms are dioecious with external fertilization. Major classes of Echinodermata include: Asteroidea - starfish Asterias Ophiuroidea - brittle stars, basket stars Echinoidea - sea urchins sand dollars Holothuroidea - sea cucumbers Crinoidea - sea lilies , feather stars PROCEDURE : Starfish are found in relatively shallow waters, and range in size from less than an inch to nearly three feet in diameter. They feed primarily on bivalves, forcing the shell to open with their tube feet, everting their stomach into the victim's body cavity, and digesting it. The larvae are known as bipinnaria and have bilateral symmetry. Starfish can perform autotomy (self-amputation) of their arms. However, if a small portion of the central disc remains attached to it, the amputated arm can then regenerate and form a new individual! Place a specimen of Asterias (starfish) on a tray preferably immersing it completely underwater, and observe the following:

Taft Wednesday, January 02, 2008 And so, it begins... Twenty-four hours from now, we should know the results of the Iowa caucuses, the first real step on the path to the Presidency. I've got to admit I'm nervous and excited in a way I've never been before in an election season. The main reason is because I usually haven't picked a favorite this early. Oh, I might have some vague ideas, but I'm not generally "married" to any of the candidates yet. I might be disappointed if some I like drop out, but I usually wait at least until after New Hampshire to start thinking about it seriously. Of course, this time around, time is much shorter. It's only a bit over a month until I get to cast my own primary vote; in the past the gap has been more like three to five months. Also, it's quite possible likely, even that when California goes to the polls with twenty-one other states on Tsunami Tuesday, or whatever they're calling it, the race will still be undecided and that California's large number of convention delegates could make the difference. Of course, I'm mainly concerned with the Democratic nomination, but it's true of the Republican race, too.

The Diversity of Living Organisms: Themes of Adaptation and Evolution What are the Echinodermata? Background Sources Background General Echinodermata includes the common sea stars, sea urchins, sand dollars, sea cucumbers and many other unique and interesting marine organisms. The term echinoderm comes from two Greek words: "echino" meaning spiny and "derm" meaning skin. A brush with either a sea urchin or a sea star in a marine aquarium's touch tank will quickly confirm the validity of the phylum's name. Body Form Echinoderms are coelomate deuterostomes. Although the adults are typically radially symmetric, the larval forms exhibit bilateral symmetry. Nearly all of the members of this phylum possess some type of an internal calcareous skeleton. Almost all echinoderms possess a unique water-vascular system. This system consists of a series of fluid-filled canals extending throughout the body and often terminating in a series of bulb-like structures known as "tube feet". Muscular contractions force water into and out of the tube feet, allowing them to expand and contract individually. Each "foot" has a muscular, suckerlike ampulla on the end that attaches to available substrates. Many of the sea stars use this unique hydraulic system to grip clams and snails, breaking open the shells for a meal. The nervous system associated with the water-vascular system is also unique. Rather than having a centrally-oriented system with a controlling "brain", there are a series of nerve networks extending into each of the various body regions. The nerve networks are connected to a central ring-like series of nerve ganglia. This unique "radial" nervous system allows the echinoderms unusual flexibility in behavior, as any portion of the body can serve as the "head" as it experiences its environment.
