Almost three-quarters of our planet is covered by water, and these watery worlds are home to an amazing variety of plant and animal life.
The open oceans may appear to be empty of life but here we find fast-swimming sailfish, fearsome sharks, massive whales, and huge sea turtles. There are also schools of smaller fish, such as herring and mackerel, as well as vitally important microscopic animal and plant plankton.
With vivid photographs and clear text, Ocean Life is a fascinating introduction to this important environment.
