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.

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.

Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.
