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.
