THE SECRET HISTORY OF SHARKS

Everything you ever wanted to know about this ancient, awesome, and threatened fish.

Prolific science writer Long, a professor of paleontology at Flinders University in Australia and author of more than 25 books, fell in love with sharks as a boy, and he maintains his enthusiasm throughout his latest, which is divided into five sections: The First Sharks, Sharks Rule, Sharks Under Pressure, The Age of the Megasharks, and Sharks Today. The author begins more than 400 million years ago. Although sharks have survived five global mass extinctions, their origin remains a mystery. “We have learned a great deal about the early origins of bony fishes, am­phibians, reptiles, and mammals in recent years through stunning new ‘transitional’ fossil finds, while there have not been any significant ad­vances in our knowledge of shark origins,” writes Long, who provides a comprehensive account of their evolution, along with that of those related creatures. He and his shark paleontologist colleagues seem like a fun bunch; readers will enjoy detours describing their frustrations and rare triumphs as they trudge over seven continents to freeze, swelter, or soak while hammering away at rocks to reveal marvels—or do the same in the lab with high-tech scanners. The author describes the dazzling variety of these fish in the ocean today and concludes with the plea to save them from extinction. Shark populations are plummeting through massive overfishing, pollution, and recreational slaughter, sadly energized by the misconception that they are man-eaters. Long writes lively, lucid prose, and while this is not a textbook, he delivers an extremely detailed education in the history, anatomy, behavior, and ecology of the extensive shark family. Long’s work makes a nice complement to Jasmin Graham’s Sharks Don’t Sink.
