The secret history of sharks

From ancient megalodons to fearsome Great Whites, this book tells the complete, untold story of how sharks emerged as Earth's ultimate survivors, by world-leading paleontologist John Long. Sharks have been fighting for their lives for 500 million years and today are under dire threat. They are the longest-surviving vertebrate on Earth, outlasting multiple mass extinction events that decimated life on the planet. But how did they thrive for so long? By developing superpower-like abilities that allowed them to ascend to the top of the oceanic food chain. John Long, who for decades has been on the cutting edge of shark research, weaves a thrilling story of sharks' unparalleled reign. 'The Secret History of Sharks' showcases the global search to discover sharks' largely unknown evolution, led by Long and dozens of other extraordinary scientists.
