Inspired by the International White Shark Symposium in 2010, Global Perspectives on the Biology and Life History of the White Shark incorporates the most important contemporary research findings into a single peer-reviewed book. This beautifully illustrated reference represents a historic change in the context of White Shark (Carcharodon carcharias) research. Once considered one of the most poorly understood and difficult sharks to study, this timely book recognizes a new sophisticated focus on the White Shark, raising its status from obscurity to enlightenment. The Global Perspectives on the Biology and Life History of the White Shark celebrates the White Shark as the most studied shark in the sea. Within the chapters one can find new insights into a vast range of topics, such as behavior, physiology, migration patterns, habitat preferences, daily activity patterns, molecular genetics, reproductive biology and new research methods. The book also delves into population monitoring and policy options for managers and researchers.

The definitive field guide to all the sharks, rays and chimaeras of eastern North America The waters off the East Coast of North America are home to an amazing variety of sharks, rays and chimaeras. This groundbreaking, comprehensive and easy-to-use field guide covers all 173 species found along the eastern seaboard of the United States and Canada, including Bermuda and the Bahamas, and extending into the Gulf of Mexico to the Yucatan Peninsula. These are all the species that are encountered in the shallow waters of estuaries and coasts and in the open ocean, including rarely seen deepsea species. Lavishly illustrated throughout, this must-have guide includes detailed species accounts describing key identification features, habitat, biology and status. It also features illustrated key guides that enable users to accurately identify species, comparison plates of similar species, dentition plates and illustrations of egg cases, where known. This an essential guide for fisheries management, trade regulation and shark conservation. The first field guide to cover all 173 species Features hundreds of color illustrations and photos Describes key features, habitat, biology and status Includes depth guides, at-a-glance icons and distribution maps Offers illustrated key guides, species comparisons and dentition plates

Features of the valid nominal species of Aprionodon Gill (isodon Valenciennes) and Hypoprion Müller and Henle (hemiodon Valenciennes, macloti Müller and Henle, and signatus Poey), plus those of a previously unrecognized species here described as Carcharhinus leiodon n.sp., are examined and compared with those of Carcharhinus Blainville. Features studied include morphometrics, vertebral numbers and other vertebral characteristics, tooth numbers, color pattern, and some other aspects of external morphology. It is concluded that on these features C. Leiodon n.sp. is entirely encompassed within the parameters of Carcharhinus, and that, although A. isodon, H. hemiodon, H. macloti, and H. signatus each extend the range of diversity of Carcharhinus in one or more features, A. isodon is not uniquely different from Carcharhinus, and there is no common pattern of difference between the three species of Hypoprion and Carcharhinus. Accordingly, and because the nature of the teeth of Aprionodon and Hypoprion has been found insufficient to warrant generic distinction from Carcharhinus, the genera Aprionodon and Hypoprion are synonymised with Carcharhinus. A diagnosis and description are given for each of the above species. The descriptions include measurements, counts, and line illustrations that show the whole shark in lateral view, underside of head, nostril, and teeth. The geographic distribution is summarized, as are also the meager biological data available on number of embryos, size at birth, size at sexual maturity, and maximum size.
