Download or read book Rays of the World written by Peter Last and published by CSIRO PUBLISHING. This book was released on 2016-12 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rays are among the largest fishes and evolved from shark-like ancestors nearly 200 million years ago. They share with sharks many life history traits: all species are carnivores or scavengers; all reproduce by internal fertilisation; and all have similar morphological and anatomical characteristics, such as skeletons built of cartilage. Rays of the World is the first complete pictorial atlas of the world’s ray fauna and includes information on many species only recently discovered by scientists while undertaking research for the book. It includes all 26 families and 633 valid named species of rays, but additional undescribed species exist for many groups. Rays of the World features a unique collection of paintings of all living species by Australian natural history artist Lindsay Marshall, compiled as part of a multinational research initiative, the Chondrichthyan Tree of Life Project. Images sourced from around the planet were used by the artist to illustrate the fauna. This comprehensive overview of the world’s ray fauna summarises information such as general identifying features and distributional information about these iconic, but surprisingly poorly known, fishes. It will enable readers to gain a better understanding of the rich diversity of rays and promote wider public interest in the group. Rays of the World is an ideal reference for a wide range of readers, including conservationists, fishery managers, scientists, fishers, divers, students and book collectors.

Download or read book Elasmobranch Biodiversity Conservation and Management written by Sarah L. Fowler and published by IUCN. This book was released on 2002 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.

Download or read book A Sea Monster s Tale written by Colin Speedie and published by Princeton University Press. This book was released on 2021-06-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few marine creatures as spectacular as the Basking Shark. At up to 11 metres in length and seven tonnes in weight, this colossal, plankton-feeding fish is one of the largest in the world, second only to the whale shark. Historically, Basking Sharks were a familiar sight in the northern hemisphere – off the coasts of Norway, Scotland, Ireland, Canada and the USA, for example. In an 18th Century world without electricity, they became the focus of active hunting for their huge livers containing large amounts of valuable oil, primarily used in lamps. Catch numbers were small enough to leave populations largely intact, but during the 20th Century a new breed of hunter joined the fray, some driven as much by a need for adventure as for financial gain. With improved equipment and experience, they exploited the shark on an industrial scale that drastically reduced numbers, leading to localised near-extinction in some areas. From the 1970’s onward a new generation took to the seas, this time with conservation in mind to identify where the shark might still be found in the waters around the British Isles, employing new technologies to solve long-standing mysteries about the behaviour of this elusive creature. Using the best of both old and new research techniques, the case was built to justify the species becoming one of the most protected sharks in the oceans. Today, the Basking Shark is a much-loved cornerstone of our natural heritage. There are positive signs that the population has stabilised and may even be slowly recovering from the damage of the past, proving that timely conservation measures can be effective. Join us on a journey amidst wild seas, places, people and conservation history in the battle to protect this iconic creature – a true sea monster’s tale.

Available in PDF, EPUB and Kindle. Book excerpt: Seahorses are instantly recognisable and have been a part of our culture for millennia, yet we still know very little about these enigmatic creatures. Steve Trewhella and Julie Hatcher have spent hundreds of hours in British waters observing native seahorses, witnessing at first hand how they behave in the wild, and how they interact with the other plants and animals in their underwater realm. With stunning photography, In the Company of Seahorses paints a rich picture of a mysterious world amongst swaying seagrass and colourful seaweeds. The accompanying text is packed with personal anecdotes describing the authors’ journey of discovery, illustrating for the first time the secretive lives of these elusive animals in British waters. By sharing one couple’s passion for an entrancing ocean icon, this book aims to inspire, inform and create a better understanding of the seahorse and its often vulnerable habitats around the British coastline.

Download or read book The Biology of Sharks and Rays written by A. Peter Klimley and published by University of Chicago Press. This book was released on 2013-07-31 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Sharks and Rays is a comprehensive resource on the biological and physiological characteristics of the cartilaginous fishes: sharks, rays, and chimaeras. In sixteen chapters, organized by theme, A. Peter Klimley covers a broad spectrum of topics, including taxonomy, morphology, ecology, and physiology. For example, he explains the body design of sharks and why the ridged, toothlike denticles that cover their entire bodies are present on only part of the rays’ bodies and are absent from those of chimaeras. Another chapter explores the anatomy of the jaws and the role of the muscles and teeth in jaw extension, seizure, and handling of prey. The chapters are richly illustrated with pictures of sharks, diagrams of sensory organs, drawings of the body postures of sharks during threat and reproductive displays, and maps showing the extent of the species’ foraging range and long-distance migrations. Each chapter commences with an anecdote from the author about his own personal experience with the topic, followed by thought-provoking questions and a list of recommended readings in the scientific literature. The book will be a useful textbook for advanced ichthyology students as well as an encyclopedic source for those seeking a greater understanding of these fascinating creatures.
