A visual guide to oceans -- their formation and extent; the life-forms they support; their value to humans; and the threats they face.
"This is a superb book. The authors are to be commended. Not only did I find the book informative and useful, but as an ichthyhologist [fish expert] and former director of a marine conservation non-governmental organization, I learned new information." - Neil Alfonso, Research Services, Canadian Museum of Nature The world's oceans contain habitats that are as different from one another as a rainforest is from a desert. Oceanography is little more than a century old, and scientists now explore the sea in specialized submersibles and scan its features from space. Oceans explores the mysteries of these fascinating worlds beneath the waves. From the coastline to the deepest trench, oceans host an astonishing variety of marine life. Some are rare, some bizarre, some of breathtaking beauty. Each form of life has adapted to the extreme conditions of ocean life in unique and fascinating ways.
