All known and relevant data and features to enable an identification of sharks of the genus Carcharhinus (BLAINVILLE 1816) are summarised and visualised in this book. The introduced species are difficult to separate for somebody who is not experienced in identifying sharks. An identification key is given to determine and to differentiate the species. For each species an extended list of characters is given including coloured figures to show the lateral and ventral view, a detailed view of nostril and teeth, and in some cases of juveniles and special characters. Further, data on body size and appearance, colouration, tooth formula and shape, numbers of vertebrae, on other internal and external characters, the geographical distribution, preferred habitat and food spectrum are presented. In addition, biological and reproductional data are included, e. g. number of young per litter, size at birth, size at sexual maturity, as well as behaviour and migrational patterns.

The study of fossil fishes has advanced significantly over the past few years, giving scientists a rare opportunity to understand the origin and early evolution of major vertebrate groups, ranging from the jawless agnathans to piscine gnathostomes (placoderms, acanthodians, chondrichthyans and osteichthyans). This book presents recent findings on the morphology, phylogeny and paleobiogeography of fossil fishes, as a tribute to Professor Meemann Chang for her contributions to paleoichthyology and to the study of early vertebrate evolution.

With a foreword by Dr. Henry Gee (Senior Science Editor of Nature), an introduction, 22 research papers by leading vertebrate paleontologists from 14 countries, and 220 photos and illustrations, this book covers important fossil forms ranging from the Paleozoic to the Cenozoic and reflects research advances based on traditional paleontological methods as well as new techniques such as CT scanning.
