Book excerpt: Les requins ? Ils sont presque à égalité avec les dinosaures dans l'imaginaire collectif. C'est l'histoire de ces animaux que cet ouvrage illustré de près de 200 reconstitutions et photographies propose de découvrir. Une histoire longue, puisque cela fait plus de 450 millions d'années que les requins existent. Une histoire qui nous conduit à découvrir des monstres du passé dont certains tutoyaient les 20 mètres de long. Ou bien des requins à la dentition impressionnante (scies circulaires, couteaux à viande longs près de 20 cm, etc) Mais aussi des requins, aujourd'hui disparus, à la morphologie invraisemblable : requins avec des brosses ou des grappins sur la tête, requins pratiquant une sorte de vol aquatique... Une histoire qui nous invite aussi à réviser certaines idées reçues : non, les requins ne sont pas des sortes de fossiles vivants qui auraient traversé les âges sans changement. Et non, les requins ne sont pas tous des monstres sanguinaires. Ainsi, certains requins fossiles étaie, dépourvus de dents ! Un livre facile à lire, écrit par LE spécialiste français des requins, riche en informations scientifiques, en sensations et en surprises.

Download or read book In the Name of Sharks written by François Sarano and published by John Wiley & Sons. This book was released on 2023-10-17 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty metres below water, the oceanographer François Sarano came face to face with a five-and-a-half metre great white shark. Seduced by the gentle elegance of this majestic creature, Sarano experienced a profound sense of affinity with her as they swam side by side, shoulder to shoulder, eye to eye, cutting a single figure through the ocean depths. It was an experience which made him realize the depth of our ignorance of the lives of sharks, leading him to become a passionate advocate for their protection. Drawing on the latest scientific research on the biology and ethology of sharks and their exceptional characteristics, this book aims to break through the barrier of prejudice and to pay homage to their true nature. Representing a last vestige of wildness, their populations are nevertheless under threat – like so many species, they have been hunted and exploited by humans. Sarano argues for a change of mindset in which we lose ourselves in the world of the other, so that each living entity, human and non-human, can take their rightful place in the broader global ecosystem.
Download or read book Ocean Life in the Time of Dinosaurs written by Nathalie Bardet and published by Princeton University Press. This book was released on 2023-11-21 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: A richly illustrated introduction to the spectacular reptiles that swam the oceans when dinosaurs roamed the land During the Mesozoic Era, 252 to 66 million years ago, dinosaurs ruled the land, but the ocean deeps were roiling with equally spectacular reptiles—including giant predators. This richly illustrated, authoritative, and accessible book introduces readers to the world of these fascinating marine animals, whose predecessors returned to the seas a few million years after the first vertebrates emerged from the water. As we meet ichthyosaurs, plesiosaurs, mosasaurs, and many others, we learn about the astonishing anatomical, physiological, and behavioral adaptations that enabled these reptiles to become ocean dwellers again. We also learn about their living descendants, including sea turtles and sea snakes. Featuring stunning artwork depicting these prehistoric ocean creatures and photographs of their fossil remains, this book invites readers to discover the enthralling past of marine reptiles in all their extraordinary diversity.

Book excerpt: Fish Physiology: Physiology of Elasmobranch Fishes, Volume 34A is a useful reference for fish physiologists, biologists, ecologists, and conservation biologists. Following an increase in research on elasmobranchs due to the plight of sharks in today’s oceans, this volume compares elasmobranchs to other groups of fish, highlights areas of interest for future research, and offers perspective on future problems. Covering measurements and lab-and-field based studies of large pelagic sharks, this volume is a natural addition to the renowned Fish Physiology series. Provides needed comprehensive content on the physiology of elasmobranchs Offers a systems approach between structure and interaction with the environment and internal physiology Contains contributions by leading experts in their respective fields, under the guidance of internationally recognized and highly respected editors Highlights areas of interest for future research, including perspective on future problems
Download or read book Evolution of Dental Tissues and Paleobiology in Selachians written by Gilles Cuny and published by Elsevier. This book was released on 2018-02-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyans possess unique anatomical features compared to other vertebrates, in particular a fully cartilaginous skeleton and a permanently renewed dentition. These characteristics make the fossilization of whole bodies difficult and consequently their fossil record consists mainly of a large number of isolated teeth. The study of their dentition is therefore of primary interest for our understanding of the evolution of this group. Beyond the dental morphology, the structure of the tissues composing the dentition has proved an important source of information, sometimes difficult to interpret, on the eating habits and the paleobiology of these animals. This book makes a thorough review of the existing theories in this field of research as well as introducing new elements from more recent studies. Through close reference to the fossil record of ancient selachians it examines what the study of dental tissue in cartilaginous fish can tell us about the evolution and the past biology of these animals, as well as what we can learn about the evolution of teeth themselves. - Focuses on the evolution of the teeth microstructure of the cartilaginous fishes - Offers a complete overview of the terminology used to describe fish tooth microstructures - Offers an overview of convergent enameloid microstructures between actinopterygians (ray-finned fishes) and chondrichthyans to enable better understanding of the evolution of this kind of tissue - Highlights the importance of isolated fossil teeth to understand the evolution of whole clades - Discusses the use of isolated fossil teeth to understand the evolution of whole clades

Book excerpt: Le requin occupe une place à part dans l'imaginaire collectif : celle de maître des océans, prédateur absolu, tueur sanguinaire assoiffé de sang, bouc émissaire chargé de tous les péchés de la création. Autant de clichés à l'emporte-pièce, nourris par des siècles d'ignorance, relayés par les médias qui ne manquent jamais une occasion d'entretenir son exécrable réputation. Nul n'a oublié le film de Steven Spielberg, Les Dents de la mer, dont les effets négatifs perdurent. A tort, car les attaques sur l'homme sont rarissimes. Le requin est avant tout un animal magnifique dont le rôle dans les océans est primordial. Elément majeur de l'échelle alimentaire, il a une fonction de régulateur indiscutable qui peut être assimilée à celle des rapaces, dans le monde des oiseaux. Tout au long de cet ouvrage, nous apprendrons à mieux connaître le requin, ou plutôt les requins, car il y en a 355 espèces. Des origines à nos jours, nous suivrons leur évolution et tenterons de comprendre l'extrême diversité de leurs formes, du minuscule squalelet qui se nourrit en prélevant une carotte de chair sur ses victimes tout en les laissant en vie, jusqu'à l'inoffensif requin baleine, plus grand poisson que la mer ait jamais porté, en passant par l'incontournable requin blanc à la triste réputation. Nous découvrirons leur biologie, leurs modes de locomotion et de apprendrons qu'on peut aussi plonger en leur compagnie. Dans la seconde partie de l'ouvrage, tout au long de dix-sept reportages, nous suivrons l'auteur autour du monde pour y découvrir un univers de beauté mais aussi d'âpreté. Adrénaline garantie. Mais nous y découvrirons aussi que le requin est gravement menacé par nos excès et que sa disparition pourrait bien précéder la nôtre de peu.
