Many animals elicit the same mythical terror and awe as sharks, and yet we know little about these elusive, highly engineered creatures. John A. Musick and Beverly McMillan bring us along on a thrilling adventure as they chase sharks from Bear Gulch, Montana, to a whale shark-feeding station in Okinawa, by way of Alaska, the Bimini islands, and the most sophisticated shark-research labs in the world. En route we discover that sharks navigate using electromagnetic signals, have a bloodhound's sense of smell, are both cold- and warm-blooded, and possess biochemical weapons, which, used properly, might indeed help fend off malignant tumors and microbes.
Musick, who has spent over thirty years as a defender of the much-maligned shark, here excavates the mysterious lives of sharks from the dark recesses of the oceans--and raising the alarm about how fishing and industry are reducing their numbers and affecting their behavior. This captivating and educational scientific exploration challenges us to rethink our relationship with sharks, leaving us with the question: Are humans the prey, or the predator?
