Sea urchins are a major component of the world ocean. They are important ecologically and often greatly affect marine communities. They have an excellent fossil record and consequently are of interest to paleontologists. Research has increased in recent years stimulated first by a recognition of their ecological importance and then because of their economic importance. Scientists around the world are actively investigating their potential for aquaculture. This book is designed to provide a broad understanding of the biology and ecology of sea urchins. Synthetic chapters consider biology of sea urchins as a whole to give a broad view. The topics of these chapters include reproduction, metabol...
This fully revised and expanded edition of Sea Urchins provides a wide-ranging understanding of the biology and ecology of this key component of the world's oceans. Coverage includes reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Other chapters consider the ecology of individual species that are of major importance ecologically and economically, including species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. In addition, six new contributions in areas such as immunology, digestive systems and community ecology inform readers on key recent developments and insights from the literature.Sea u...

Sea urchins don't have brains, and yet sea urchin bodies are well-developed to detect the environment. This book explores body parts sea urchins use instead, including an interior water pump that allows the creatures to move about and hold on to food. Fun and bizarre facts are spread throughout the narrative, like how a sea urchin turns itself inside out upon growing into its adult stage. Young readers will be delighted by these ocean creatures.
Describes the physical characteristics, behavior, habitat, diet, and hunting style of sea urchins.
This book provides a practical guide to experimental methods for studying the development invertebrate deuterostomes as animal model systems. The chapters provide detailed experimental protocols that cover a broad range of topics in modern experimental methods. Topics covered range from rearing embryos to the care of adult animals, while also presenting the basic experimental methods including light and electron microscopy, used to study gene expression, transgenics, reverse genetics, and genomic approaches.* Covers a wide range of methods, from classical embryology through modern genomics* Discusses animals related to vertebrates, providing a valuable evolutionary perspective* Includes a practical guide to the use of sea urchins in the teaching laboratory
"Sea urchins are harvested worldwide, the majority destined for the Japanese market. Japan is by far the world's largest importer and consumer of sea urchin roe. In 2002, Japan imported about 18,525 metric tons (mt) of live sea urchins and sea urchin roe valued at about 247 million dollars, an increase of more than ten-fold in volume and 12-fold in value from 1975. Much of this increase was due to good demand, decreased domestic harvest, and consequent rise in price for sea urchin roe. Fresh sea urchin roe was the dominant product imported into Japan, representing as much as 49 percent in value in 2002. The United States has become the largest supplier of fresh roe to Japan, providing over 4...
