This Special Issue of Marine Drugs gathers recent investigations on the proteomes, metabolomes, transcriptomes, and the associated microbiomes of marine jellyfish and polyps, including bioactivity studies of their compounds and more generally, on their biotechnological potential, witnessing the increasingly recognized importance of Cnidaria as a largely untapped Blue Growth resource for new drug discovery. These researches evoke the outstanding ecological importance of cnidarians in marine ecosystems worldwide, calling for a global monitoring and conservation of marine biodiversity, so that the biotechnological exploitation of marine living resources will be carried out to conserve and sustainably use the natural capital of the oceans.

This book provides new insights into the universality of biological systems in animal reproduction and development by a comparative study of a variety of mechanisms in animals ranging from basal invertebrates to vertebrates, including mammals. Animals accomplish genetic diversity through meiosis and fertilization, and during embryogenesis animals must produce specialized cell types, including germ cells, in accordance with their individual body plan. This series of phenomena is essential to the continuity of life in the animal kingdom, and animals show various reproductive and developmental strategies. This volume, comprising four parts, reviews animal kingdom diversity, including reproductive strategies and germ cell differentiation mechanisms (Part 1), sex determination and differentiation (Part2), the mechanisms of fertilization (Part 3), and body axis formation (Part 4). Readers will find descriptions of the reproduction or development of 180 species, 13 phyla, 35 classes, 74 orders, 117 families, and 151 genera in this book. Of particular interest is the diversity of molecules and mechanisms used to achieve the same biological purpose in different animals. Undergraduates, graduate students, and professional scientists who want a deeper understanding of animal reproductive and developmental mechanisms will find this book to be of great value.

Scyphozoa have attracted the attention of many types of people. Naturalists watch their graceful locomotion. Fishermen may dread the swarms which can prevent fishing or eat larval fish. Bathers retreat from the water if they are stung. People from some Asiatic countries eat the medusae. Comparative physiologists examine them as possibly simple models for the functioning of various systems. This book integrates data from those and other investigations into a functional biology of scyphozoa. It will emphasize the wide range of adaptive responses possible in these morphologically relatively simple animals. The book will concentrate on the research of the last 35 years, partly because there has been a rapid expansion of knowledge during that period, and partly because much of the previous work was summarized by books published between 1961 and 1970. Bibliographies of papers on scyphozoa were included in Mayer (1910) and Kramp (1961). Taxonomic diagnoses are also included in those monographs, as well as in a monograph on the scyphomedusae of the USSR published by Naumov (Naumov, 1961). Most impor tantly, a genenttion of scyphozoan workers has used as its 'bible' the monograph by F.S.Russell (1970) The Medusae of the British Isles. In spite of its restrictive title, his book reviews most of the information on the biology of scyphozoa up to that date.

An introduction to these bizarre and beautiful creatures of the sea, filled with color photos and illustrations: “Fascinating.”—Boing Boing Jellyfish are the oldest multi-organed life form on the planet, having inhabited the ocean for more than five hundred million years. With their undulating umbrella-shaped bells and sprawling tentacles, they are compelling and gorgeous, strange and dangerous. In many places they’re also vastly increasing in number, and these population blooms may be an ominous indicator of the rising temperatures and toxicity of the oceans. Jellyfish presents these aquarium favorites in all their glory. Fifty unique species, from the purple people eater to black sea nettles, are presented in stunning photos along with the most current scientific information on their anatomy, history, distribution, position in the water, and environmental status. Foremost jellyfish expert Lisa-ann Gershwin provides an insightful look at the natural history and biology of each of these spellbinding creatures, plus a timely take on their place in the rapidly changing and deteriorating condition of the oceans. Learn about immortal jellyfish who live and die and live again—as well as those who camouflage themselves amid sea grasses and shells, hiding in plain sight. Discover the jellyfish that’s the world’s most venomous animal, and the jellyfish that helped scientists win the Nobel Prize. They’re all here and more in this delightful volume. “A thorough coverage of jellyfish history, biology and ecology. Gershwin, a marine biologist who has discovered over 200 new species of jellyfish, does an excellent job of combining a compelling narrative of 50 different jellyfish with luscious, I-can’t-believe-they’re-real photos.”—Boing Boing

`Jellyfish', a group that includes scyphomedusae, hydromedusae, siphonophores and ctenophores, are important zooplankton predators throughout the world's estuaries and oceans. These beautiful creatures have come to public attention as featured exhibits in aquaria and in news headlines as invaders and as providers of genes used in biomedical research. Nevertheless, jellyfish are generally considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen and fish farms, and competing with fish and eating fish eggs and larvae. There is concern that environmental changes such as global warming, eutrophication, and over-fishing may result in increased jellyfish populations. The literature reviews and research papers in this volume explore the interactions between jellyfish and humans. Papers cover the medical aspects of jellyfish stings, jellyfish as human food and jellyfish fisheries, interactions of jellyfish and fish, effects of environmental changes on jellyfish, effects of introduced ctenophores on the Black Sea ecosystem, factors causing increases or concentrations of jellyfish, and others aspects of jellyfish ecology. This is an important reference for students and professional marine biologists, oceanographers, fishery scientists, and aquarists.

Jellyfish generally are considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen, killing fish in aquaculture pens, and being both predators and competitors of fish. There is concern that environmental changes such as global warming, eutrophication, over-fishing, and coastal construction may benefit jellyfish populations. During this past decade following the first Jellyfish Blooms volume, some species have bloomed more frequently, expanded their range, and caused more problems for humans. Mnemiopsis leidyi, the ctenophore that invaded the Black Sea in the 1980s and damaged fisheries, now also blooms in the North, Baltic, and Mediterranean seas. Nemopilema nomurai, a giant Asian jellyfish, has bloomed frequently during this decade, causing severe damage to the Japanese fishing industry. Jellyfish Blooms: Interactions with Humans and Fisheries is the fourth volume in this series. Syntheses and original research articles address the question if jellyfish have increased globally and what factors may have contributed to the abundance of jellyfish. This volume is the most extensive to date, containing papers from all continents (except Antarctica) on scyphozoans, hydrozoans, cubozoans, staurozoans, and ctenophores, and on the fate of jellyfish blooms. This is a key reference for students and professional marine biologists, oceanographers, and fishery scientists and managers. Previously published in Hydrobiologia, vol. 690, 2012​
