The Extreme Life of the Sea exposes the eternal darkness of the deepest undersea trenches to show how marine life thrives against the odds, describing how flying fish strain to escape their predators, how predatory deep-sea fish use red searchlights only they can see to find and attack food, and how, at the end of her life, a mother octopus dedicates herself to raising her batch of young. This wide-ranging and highly accessible book also shows how ocean adaptations can inspire innovative commercial products--such as fan blades modeled on the flippers of humpback whales--and how future extremes created by human changes to the oceans might push some of these amazing species over the edge.
