Agile, sleek, and precise, sharks display many qualities we can admire and appreciate. These marvels of evolution have adapted to thrive in every major aquatic realm on the planet, from frigid Arctic waters through temperate but stormy seas and on into the tropics. However, few places on Earth are home to the amazing diversity of shark species that beautify the shallow waters of Florida and the Bahamas. In this first-ever book dedicated to the sharks of this region, biologist Jeffrey C. Carrier reveals the captivating lives of these large marine predators and describes how they have survived for over 400 million years. Guiding readers through basic biology, key attributes, and identification tips, the book explores what makes sharks such successful apex predators. Carrier explains fascinating phenomena, including the reason for the bizarre shape of the hammerhead, how a bull shark is able to swim hundreds of miles up freshwater rivers, what lies behind sharksâ€™ remarkable capability to learn and remember, and why many scientists believe that they are equipped with the most sophisticated sensory systems in the animal kingdom. With the stunning full-color underwater photography of Andy Murch, Jillian Morris, and Duncan Brake, Sharks of the Shallows brings boaters, fishers, divers, and shark lovers directly alongside these unfairly maligned creatures. And not a moment too soon! Sharks are experiencing stresses unlike any in their long history, and are struggling to survive in a changing ocean. They will continue to grace our coastlines only if we care enough to understand them.
This guide contains useful and easily accessible information on a wide range of topics concerning sharks and their interaction wih divers. The authors main concern is that sharks should be understood rather than feared and that through our knowledge of sharks will come a deeper appreciation of their nature and desire that they should be conserved rather than hunted to extinction.
The Tenth Edition of Morrissey and Sumich’s classic text, Introduction to the Biology of Marine Life continues to enlighten and engage students on the many wonders of marine organisms and the remarkable environments in which they live. This updated edition includes coverage of recent breakthroughs in research and technology, and maintains the accessible student-friendly style for which it is known. A Student Companion Website provides resources to expand the scope of the textbook and makes sure students have access to the most up-to-date information in marine biology. Students will benefit from a variety of study aids, including chapter outlines, an interactive glossary, animated flash cards, and review questions. Carefully chosen links to relevant Web sites enable students to explore specific topics in more detail
For many years, brief encounters between sharks and humans could leave the latter with a vivid memory of the much-maligned fish but no convenient means of identifying it more specifically. With the publication of The Sharks of North American Waters in 1983, everyone from the experienced ichthyologist to the weekend angler had access to concise descriptions and accurate, detailed drawings in this handy field guide to more than one hundred species. All species that have been reported within five hundred nautical miles of U.S. and Canadian shores (plus a few deep-water species from adjacent areas) are illustrated, with summaries of diagnostic characteristics, similar species, geographic range, biology, reproduction, utility, and fishing methods. An illustrated key to the families of sharks, family descriptions, and species characteristics makes field identification simple. Also included is a general account of the evolution of sharks, their anatomy, reproduction, and distribution.
Das neue Buch des SPIEGEL-Bestsellerautors Fürsorgliche Eichhörnchen, treu liebende Kolkraben, mitfühlende Waldmäuse und trauernde Hirschkühe – sind das nicht Gefühle, die allein dem Menschen vorbehalten sind? Der passionierte Förster und Bestsellerautor Peter Wohlleben lehrt uns das Staunen über die ungeahnte Gefühlswelt der Tiere. Anhand neuester wissenschaftlicher Erkenntnisse und anschaulicher Geschichten nimmt er uns mit in eine kaum ergründete Welt: die komplexen Verhaltensweisen der Tiere im Wald und auf dem Hof, ihr emotionales und bewusstes Leben. Und wir begreifen: Tiere sind uns näher, als wir je gedacht hätten. Faszinierend, erhellend, bisweilen unglaublich!
This guidebook, with its brief, informative text and 408 color illustrations, is designed for the fishwatcher, that inquisitive personwhether swimmer, tidepool watcher, skin or scuba diver, or fishermanwho wants to know something about the beautiful and abundant marine life from Labrador to Trinidad. The 378 fish species that are described in words and pictures have been chosen as those most commonly sighted by divers or shoreline visitors, taken by fishermen or collectors, or found in the marketplace. Two maps assist the reader in locating the range of particular fishes, and there is a section on diving timps for beginners.
