Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world’s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world’s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to ‘bloom and bust’, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century. ​

Our oceans are becoming increasingly inhospitable to life—growing toxicity and rising temperatures coupled with overfishing have led many marine species to the brink of collapse. And yet there is one creature that is thriving in this seasick environment: the beautiful, dangerous, and now incredibly numerous jellyfish. As foremost jellyfish expert Lisa-ann Gershwin describes in Stung!, the jellyfish population bloom is highly indicative of the tragic state of the world’s ocean waters, while also revealing the incredible tenacity of these remarkable creatures. Recent documentaries about swarms of giant jellyfish invading Japanese fishing grounds and summertime headlines about armadas of stinging jellyfish in the Mediterranean and Chesapeake are only the beginning—jellyfish are truly taking over the oceans. Despite their often dazzling appearance, jellyfish are simple creatures with simple needs: namely, fewer predators and competitors, warmer waters to encourage rapid growth, and more places for their larvae to settle and grow. In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change. Despite their role as harbingers of marine destruction, jellyfish are truly enthralling creatures in their own right, and in Stung!, Gershwin tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations. She takes readers back to the Proterozoic era, when jellyfish were the top predator in the marine ecosystem—at a time when there were no fish, no mammals, and no turtles; and she explores the role jellies have as middlemen of destruction, moving swiftly into vulnerable ecosystems. The story of the jellyfish, as Gershwin makes clear, is also the story of the world’s oceans, and Stung! provides a unique and urgent look at their inseparable histories—and future.

`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 form spectacular population blooms and there is compelling evidence that jellyfish blooms are becoming more frequent and widespread. Blooms have enormous ecological, economic, and social impacts. For example, they have been implicated in the decline of commercial fisheries, they block the cooling water intakes of coastal industries and ships, and reduce the amenity of coastal waters for tourists. Blooms may be caused by overfishing, climate change, and coastal pollution, which all affect coastal waters around the world. Jellyfish Blooms: Causes, Consequences and Recent Advances presents reviews and original research articles written by the world’s leading experts on jellyfish. Topics covered include the evolution of jellyfish blooms, the impacts of climate change on jellyfish populations, advances in acoustic and molecular methods used to study jellyfish, the role of jellyfish in food webs and nutrient cycles, and the ecology of the benthic stages of the jellyfish life history. This is a valuable resource for students and professional marine biologists, fisheries scientists, oceanographers, and researchers of climate change.

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​

A former ocean scientist goes in pursuit of the slippery story of jellyfish, rediscovering her passion for marine science and the sea's imperiled ecosystems. Jellyfish are an enigma. They have no centralized brain, but they see and feel and react to their environment in complex ways. They look simple, yet their propulsion systems are so advanced engineers are just learning how to mimic them. They produce some of the deadliest toxins on the planet and yet are undeniably alluring. Long ignored by science, they may be a key to ecosystem stability. Juli Berwald's journey into the world of jellyfish is a personal one. Over a decade ago she left the sea and her scientific career behind to raise a family in landlocked Austin, Texas. Increasingly dire headlines drew her back to jellies, as unprecedented jellyfish blooms toppled ecosystems and collapsed the world's most productive fisheries. What was unclear was whether these incidents were symptoms of a changing planet or part of a natural cycle. Berwald's desire to understand jellyfish takes her on a scientific odyssey. She travels the globe to meet the scientists who devote their careers to jellies, hitches rides on Japanese fishing boats to see giant jellyfish in the wild, raises jellyfish in her dining room, and throughout it all marvels at the complexity of these alluring and ominous biological wonders. Gracefully blending personal memoir with crystal-clear distillations of science, Spineless reveals that jellyfish are a bellwether for the damage we're inflicting on the climate and the oceans and a call to realize our collective responsibility for the planet we share.
