From the back cover:
Sharks have been cruising our planet's waters for millions of years. They were here long before us. They were here long before the dinosaurs.
Sharks are a window into the distant past. Into deep time.
See how the most legendary ocean dwellers got their start. And how they became the sharks we know today.
