Everyone's heard of the Great Whites. But most people know little of the hundreds of other types of sharks that inhabit the world's oceans. Written by two of the world's leading authorities and superbly illustrated by wildlife artist Marc Dando, this is the first comprehensive field guide to all 440-plus shark species. Color plates illustrate all species, and detailed accounts include diagnostic line drawings and a distribution map for each species. Introductory chapters treat physiology, behavior, reproduction, ecology, diet, and sharks' interrelationships with humans.

The cookie cutter shark lives in the deep Gulf, looks like an Italian sausage with bulging eyes, and glows in the dark. It feeds by attaching itself to a sperm whale and gnawing hunks of flesh.

Often misidentified as a shark, the smalltooth sawfish is really a ray and may be in danger of disappearing in Gulf environs. The twenty to thirty teeth on each side of its snout work well for rooting up food from the sandy bottom or slashing through schools of prey. But the teeth tangle easily in commercial fishing nets.

The Okefenokee Swamp, located in southeastern Georgia and northern Florida, is the largest freshwater wetland in the United States. In this illustrated guide to the fishes of the swamp, Joshua Laerm and B. J. Freeman provide descriptions and drawings of thirty-six species, ranging from the American eel to the speckled madtom, chain pickerel, and blackbanded darter. For each fish, the authors include latinate, common, and variant names and discuss differences from similar species, local habitats as well as occurrences beyond the Okefenokee, and feeding and mating patterns.

Since the award-winning first volume, The Biology of Sharks and Their Relatives, published in 2004, the field has witnessed tremendous developments in research, rapid advances in technology, and the emergence of new investigators beginning to explore issues of biodiversity, distribution, physiology, and ecology in ways that eluded more traditional studies. As an entirely new companion volume, Sharks and Their Relatives II: Biodiversity, Adaptive Physiology, and Conservation brings you up to speed on these significant changes, specifically...

Fisheries science in North America is changing. This is the first comprehensive book to look at the past, present and future of fisheries science in North America. The authors review the current science and develop informed opinions about the future.

In the last 20 years, research activity using the zebrafish Danio rerio has increased dramatically, due in part to the ease of breeding and raising them, their genetic tractability, embryonic accessibility, and their imaging potential. In Zebrafish: Methods and Protocols, expert researchers provide a collection of experimental techniques for the genetic modification, manipulation, and in vivo live imaging of zebrafish. This volume collects sophisticated and practical techniques, including several not yet widely known, from laboratories around the world. Written in the...

Oryzias latipes, known as medaka, is a model organism from East Asia. Breeding of this small, egg-laying freshwater teleost fish has long been popular among hobbyists in Japan. Now, as biological science has entered the genome era, the medaka provides significant advantages that make it one of the most valuable vertebrate models: a large collection of spontaneous mutants collected over a century, the presence of highly polymorphic inbred lines established over decades, and a recently completed genome sequence. This book is the first comprehensive monograph to cover a variety of...

Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths,...

Between the surface of the sea and depths of two hundred meters lies a remarkable range of fish, generally known as pelagics, or open-ocean dwellers. These creatures are among the largest, fastest, highest-leaping, and most migratory fish on the entire planet. Beautifully adapted to their world, they range from tiny drift fish and plankton-straining whale sharks to more streamlined predators such as tuna, marlin, sailfish, and wahoo.
