The waters of the northeast Atlantic and Mediterranean Sea are home to an amazing variety of sharks, rays and chimaeras. This comprehensive and easy-to-use field guide covers all 146 species found in the Mediterranean, the waters of the European Atlantic and Iceland, along all the Scandinavian coasts, in the Black Sea and as far south as the Canary Islands. Detailed species accounts describe key identification features, habitat, biology and status. Every species account comes with a colour distribution map, a depth guide, at-a-glance icons and colour illustrations. This must-have field guide also features illustrated key guides that enable you to accurately identify down to species, comparison plates of similar species, illustrations of eggcases where known and plates of teeth.

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.

Like many coastal cities, Alexandria must deal with the problems arising from competition and conflict over limited resources. However, that which sets Alexandria apart is a conflict between Alexandria today and the city that Alexandria has been, i.e. the archaeological remains of its past. Must antiquities conservation give way to urban renewal? 27 contributions from relevant disciplines open the way to a solution allowing Alexandria to harmonize its past and its present and thus weave a unified vision of its future.
