Book Description
Echinoderms, including feather stars, seastars, brittle stars, sea urchins and sea cucumbers, are some of the most beautiful and interesting animals in the sea. They play an important ecological role and several species of sea urchins and sea cucumbers form the basis of important fisheries. Over 1000 species live in Australian waters, from the shoreline to the depths of the abyssal plain and the tropics to Antarctic waters. Australian Echinoderms is an authoritative account of Australia’s 110 families of echinoderms. It brings together in a single volume comprehensive information on the identification, biology, evolution, ecology and management of these animals for the first time. Richly illustrated with beautiful photographs and written in an accessible style, Australian Echinoderms suits the needs of marine enthusiasts, academics and fisheries managers both in Australia and other geographical areas where echinoderms are studied.

Book Description
Echinoderms play an important ecological role in marine communities, especially in relation to food chains, occupying diverse trophic levels such as herbivores, carnivores, detritivores and omnivores in the marine environment. These animals feed on many different kinds of food but the majority eat only small particles of edible matter suspended in the water or lying as detritus on the sea bottom. Although echinoderms occur at all depths from the intertidal to the abyssal zones and are present throughout all of the world's oceans, their distribution is limited by the composition and topography of the sea-bed, by temperature and pressure differences according to locality and depth, and by salinity and food supply. This book discusses echinoderms and their habitual environments as well as their reproductive biology and the ecology in which they form their habitats.

Book Description
Echinoderms, the star fish skeletons that beachcombers collect, are brilliantly colored and intricately ornamented creatures in their natural habitat. This reference features over 130 color photographs of five classes of echinoderms (sea stars, brittle stars, sea urchins, feather stars, and sea cucu

Book Description
Sea urchins and sea cucumbers are highly sought after delicacies growing in popularity globally. The demand for these species is rapidly outpacing natural stocks, and researchers and seafood industry personnel are now looking towards aquaculture as a means of providing a sustainable supply of these organism. Echinoderm Aquaculture is a practical reference on the basic biology and current culture practices for a wide range of geographically diverse echinoderm species. Echinoderm Aquaculture begins by examining the basic ecology and biology of sea urchins and sea cucumbers as well as the breadth of uses of these organisms as a source of food and bioactive compound. Subsequent chapters delineate the specific species of interest invarious geographic regions from around the world. Together, chapters provide a comprehensive coverage of culture practices. Echinoderm Aquaculture is a practical reference for researchers and industry personnel, and will serve as an invaluable resource to this rapidly growing segment of the aquaculture industry.

Book Description
Physiology of Echinoderms is an 11-chapter book that begins by elucidating the feeding, digestion, and excretion of specific echinoderms. The critical role of amoebocytes in the excretion process involved in these organisms is also explained. This book also describes several aspects of importance to these organisms, including salinity tolerance, osmoregulation, ionic regulation, chemical composition, neural control of locomotion, biochemical affinities, toxins, and immunology. The organisms' physiology in sensory, water vascular system, respiratory system, spawning, neurosecretion, nerves, and muscles are also explained.

Book Description
Echinoderms are now considered as a biological and geological model that underlies researches of primary importance. The extent of the contributions made by the International Echinoderm Conferences to various fields of research is attested by the scope covered by presentation at the international conferences. These proceedings contain the complete papers or abstracts of all the presentations and posters presented at the eighth International Echinoderm Conference, held in Dijon, France in September, 1994. Coverage includes: general; extinct classes; crinoids; asteroids; ophiuroids; holothuroids; and echinoids.

Book Description
The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.

Book Description
This book compiles for the first time the development of echinoderm research in Latin America. The book contains 17 chapters, one introductory, 15 country chapters, and a final biogeographic analysis. It compiles all the investigations published in international and local journals, reports, theses and other gray literature. Each chapter is composed of 7 sections: introduction describes the marine environments, and main oceanographic characteristics, followed by a history of research account divided by specific subjects. The next section addresses patterns of distribution and diversity. A specific section would explain fishery or aquaculture activities. The next sections deal with environmental and anthropogenic threats that are affecting echinoderm, and any conservation or management action. Finally, a section with conclusions, needs and new lines of research. The book will include two appendixes with species lists of all echinoderms with bathimetric data, habitat and distribution.

Book Description
This is the most comprehensive photo guide to the starfishes and other tropical Indo-Pacific echinoderms. This book covers the region from the Red Sea to Hawaii, the Marshall Islands, and Guam.Inside the book: • Photographs of 450+ species, including 126 starfish of the region; • 100+ species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book; • Special attention was given to echinoderm associates and predators, photographs of 60 of them are included; • Every effort was made to reduce disturbance to sea creatures. This book is a field guide, it provides easy identification of commonly encountered starfishes, brittle stars, feather stars, sea urchins, and sea cucumbers that can be found and photographed in depths and regions accessible to recreational diving. It is designed for divers, underwater photographers, snorkelers, beachcombers, and nature lovers. Photographs, showing color variations are included. The validity of species names was checked with the help of the World Register of Marine Species (WoRMS).
