This volume presents a broad panorama of the current status of research of invertebrate animals considered belonging to the phylum Cnidaria, such as hydra, jellyfish, sea anemone, and coral. In this book the Cnidarians are traced from the Earth’s primordial oceans, to their response to the warming and acidifying oceans. Due to the role of corals in the carbon and calcium cycles, various aspects of cnidarian calcification are discussed. The relation of the Cnidaria with Mankind is approached, in accordance with the Editors’ philosophy of bridging the artificial schism between science, arts and Humanities. Cnidarians' encounters with humans result in a broad spectrum of medical emergencies that are reviewed. The final section of the volume is devoted to the role of Hydra and Medusa in mythology and art.

Cnidarians are elegant and dazzling aquatic organisms, but despite their beauty they are known to be a threat in many coastal areas around the world. Several species of cnidaria living in tropical or sub-tropical areas are remarkably dangerous, but many Mediterranean species can also cause serious health problems. Really, cnidarians (sea anemones, corals, medusae) are considered among the most dangerous and venomous organisms, thanks to the occurrence in their tissues of batteries of intracellular capsules (nematocysts or cnidocysts) produced by the Golgi apparatus of specialized cells (nematocytes or cnidocytes) from which the phylum Cnidaria takes the name (from the Greek κνίδη = nettle). The consequences of human encounters with cnidarians vary widely, from simple skin irritation to serious anaphylactic manifestations in sensitive subjects. During the last few decades, cnidarians have been perceived as increasingly dangerous due to recurrent jellyfish outbreaks which constitute a threat both for human health and economy and for the environmental equilibrium. In addition, the occurrence of alien species, whose spread is facilitated by human activities, environmental changes, global warming, or man-made modifications of the natural features of territories, pose new and serious challenges to environmental management. For all these reasons, cnidarians can be viewed as a problem.Nevertheless, cnidarians are also viewed with particular interest due to their potential in the field of natural products. Scientists have realized the potential of natural resources hidden in aquatic environments for the development of new drugs or bioactive substances with wide potential use. At present, an enormous scientific literature is available about the value of cnidarian products as potential therapeutic agents, in human nutrition, or for other applications. As such, these organisms can also be reasonably considered a resource.Taking into consideration these two main aspects, this book aims to collect the experiences and recent research data on cnidarians and review present knowledge on the subject.

Download Biology and Ecology of Venomous Marine Cnidarians Book in PDF, ePub and Kindle
Seas and oceans cover 71 % of the earth’s surface and they are home to 80% of all life found on the planet . Among the different components of marine life, the phylum Cnidaria (formerly Coelenterata) has been reported to be responsible for more envenomations than any other marine phylum. It is believed that 2% of its known 11000 species are venomous to humans. Incidents caused by jellyfish are common all around the globe, with serious manifestations and occasional deaths reported in some countries. The Australian box jellyfish, Chironex fleckeri , has been reported to be very dangerous to humans, as contact with its tentacles can provoke immediate cardiovascular collapse and death within minutes. Though other volumes on venomous marine fauna are available, this is the first comprehensive book focusing on venomous marine cnidarians. It is a valuable text-cum-reference resource for researchers, teachers and students of various disciplines, including fisheries science, marine biotechnology and marine biology and for university and college libraries. It is also a useful guide for beachgoers, divers, physicians and environmentalists.

Download Biology of the Integument Book in PDF, ePub and Kindle
The integument plays an important role in the survival of meta zoans by separating and protecting them from a hostile environ ment. Its function ranges from protection against injury and in fection; partlcipation in the regulation of body temperature and water balance, to respiratory activity, monitoring of the environ ment and production of signals related to behaviour. All these result from specific structural, biochemical and physiological properties of intra-and extracellular components of the integu ment. Thus its characterization can be best accomplished by a multidisciplinary approach with authors specialized in different fields of science. This multi-author book, in two volumes, provides an up-to date survey of the literature. The first volume deals with the integument of invertebrates, the second with that of vertebrates, both organized primarily on a phylum basis. As the level of knowledge on the integument of phyla differs considerably, the information provided is correspondingly either limited or con densed. For some of the smaller groups of invertebrates little information is available, as often only a few electron micrographs are to be found in the literature; on the other hand, from the large body of knowledge existing for vertebrates, particularly for mammals, no complete overview can be provided, but publica tions giving access to further information have been reviewed critically.
