Djupfest - Sør-Trøndelag / 6 meters / 9.25.2005) Phylum: Echinodermata Norwegian: pigghuder Echinodermata includes exclusively marine species. No echinoderms exist on land or in fresh water. The name originates from Greek and means spiny skin. Not all have spines in their skin, although it is quite common. An outer layer of calcareous material is typical. It may form a shell as in the sea urchins , or plates connected by a flexible material, as in the sea stars . Most echinoderms live their adult lives on the bottom, clinging to the ground with hydraulic suckers. Hydraulics (sea water) is used to nutrition transport nutrition around the body, as well. Sperm and eggs are released in the water. The larvae live their first phase in the water before they attach themselves to the seabed.

Indeed, disarticulated echinoderm plates are major constituents of Phanerozoic carbonates , especially from the Mississippian. Deterostomes - thus closely related to hemichordates and chordates. Potential synapomorphies of Echinoderms and Chordates: Deuterostomous development Hollow nerve cord (only a short segement in echinoderms, hollow for whole length in chordates). Echinoderm characteristics Exclusively marine: Echinoderms lack osmoregulatory mechanisms that might allow them to live in brackish or fresh water. Skeleton is internal test comprised of individuals plates of porous high-Mg calcite. In life, the pores are occupied by a protein matrix and dermal cells. Such skeletal tissue is known as stereom. Carbonate petrologists typically call the pores meat holes . Calcite crystals are aligned such that optically, each skeletal element which act optically as individual birefringent element. One portion of the coelom develops into water vascular system Dissection This system is passively involved in gas exchange, maintainance of posture, and locomotion.

The Echinoderms have three features that distinguish them from other phyla; radial symmetry , the calcareous mesodermal skeleton and the water vascular system . The fossil record goes back to the Cambrian . It is believed that the phylum originated from a sessile suspension feeder with a circle of five branching arms similar to a lophophore. And that in free-living ancestors the body axis turned so that the mouth faced downwards, and the arms developed to serve a locomotory function. It is thought that the ampulla (hydraulic reservoir for each foot) that allows each foot to be individually controlled also developed as the animals became free-living. In some the calcareous skeleton is a loose association of plates, while in others it has fused to form a rigid test around the animal. The function of the

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.

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.

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.

The books used for the identification are listed: bibliography Echinoderms are exclusively marine, they seem to be a monophyletic group characterised by a fivefold radial symetry, an internal skeleton and an internal water vascular system.

ABSTRACT: Autotomy and regeneration are widespread in many groups of invertebrates and vertebrates, such as annelids, crustaceans, amphibians, and reptiles. Regeneration is common in all classes of Echinodermata and prevalent in ophiuroid brittle stars. Moorea, French Polynesia was surveyed for species of brittle stars living on coastal areas of the island in different habitats. Ophiuroid populations were sampled in habitats such as a mangrove marsh, a sandy beach with coral rubble and a jetty with coral rubble and conglomerate coral to determine percentages with regenerating arms. Macrophiothix longipeda (Lamarck 1816) from the mangrove marsh and two populations of Ophiocoma scolopendrina (Lamarck 1816) from the beach and jetty were studied to determine if there were differences in experimental rates of arm regeneration after induced autotomization. Each habitat was colonized by distict ophiuriod assemblages and had different percentages of regenerating individuals; M. longipeda was found to be regenerating multiple arms simultaneously and had the highest rate of regeneration. Regeneration rates differed by species; mostly likely influenced by habitat, ecology and biology of each species.
