Book Description
This is a reprint of the book Sharks of the Order Carcharhiniformes, first published in 1988. The book is a general review, taxonomic revision and phylogenetic analysis of the carcharhinoids, the largest group of living sharks, which comprises almost 60% of the known shark species. Students of shark biology have been hampered by the lack of a comprehensive and rigorous account of shark morphology. With this work, Dr. Compagno offers not only the most comprehensive and detailed account of this important group but also one of the most comprehensive modern anatomic and phylogenetic studies on cartilaginous fishes available. It is an essential reference not only for researchers on carcharhinoids but also for those who study other families of sharks and for paleontologists interested in this ancient group of fishes. The book begins with a general account of carcharhinoid sharks. Chapters two through eleven include detailed discussions of character systems used in taxonomic and phylogenetic analysis of carcharhinoids. Chapter twelve defines the Order Carcharhiniformes, lists its families and includes a taxonomic key to the families. Chapters thirteen through twenty review the eight carcharhinoid families and chapter twenty-one is an extended discussion of the phylogeny of carcharhinoids with cladistic analysis of taxa at various levels. L. J. V. Compagno is Curator of Fishes and Head of the Shark Research Center at Iziko - Museums of Cape Town, South Africa.

Book Description
Sharks have existed on earth for more than 400 million years, surviving the extinction event that wiped out the dinosaurs. They are highly evolved apex predators that are essential in keeping the balance of the ecosystem they thrive in. Sharks are often characterized by their highly distinctive triangular dorsal fin and jaws lined with sharp teeth. They vary greatly between species and while some such as the tiger shark and bull shark deserve the reputation for being aggressive hunters, there are many species that are docile and peaceful, such as the whale shark, a gentle giant that feeds on plankton and krill. They have keen senses that make them extremely skilled hunters. Aside from their acute sense of smell, sharks are able to detect electrical signatures in the water through special electroreceptors called the ampullae of Lorenzini. Sharks have been a source of fascination for mankind for centuries and despite there only being a handful of fatalities from shark attacks, media coverage and movie portrayals have led the public to believe that they are ferocious killing machines. Although some species are particularly dangerous, the majority of sharks tend to avoid humans in the water and will co-exist peacefully. However, more than 100 million sharks are slaughtered each year for consumption, trophy status, medicine, and out of fear, proving that sharks have more to fear from us than we do from them. As predators, sharks are incredibly important in maintaining the balance of the marine ecosystem and there are an increasing number of conservation initiatives helping to preserve these magnificent creatures in their natural habitats. This book explores the anatomical characteristics, various habitats and diet, as well as the reproductive behavior of nine species including the fearsome great white shark, the gregarious leopard shark, and the bizarre goblin shark.

Book Description
This important and exciting title represents the first authoritative volume focussed on pelagic (open ocean) sharks as a group. Virtually every pelagic shark expert in the world has contributed to this landmark publication which includes the latest data and knowledge on pelagic shark biology, fisheries, management, and conservation. Pelagic sharks face unprecedented levels of exploitation in all the world's oceans through both direct fisheries and by-catch, and effective management for these species is contingent upon solid science and data, which this book brings together for the first time. All those involved in shark biology will need to have a copy of this book.
