Now that a whale is too big for her tank, she is going to be returned to the sea. In all the great vastness of the ocean, will she be able to find a friend? "A fascinating tour de force."--"Kirkus Reviews." Full color.

This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.

Virtually an encyclopedia of the undersea world, this magnificent and comprehensive volume covers all aspects of life in the oceans. It is illustrated throughout with over 385 photographs, plus maps and diagrams.

The marine world is an immense, three-dimensional living space inhabited by marine life that varies from the mundane to the bizarre. Its salty influence extends up river estuaries, over seashores and inland with brine-laden spray. The Marine World covers all those organisms that live in, on and around the ocean bringing together in a single text everything from the miniscule to the immense. With chapters on marine bacteria, plants, fungi and protozoa, as well as all the major groups of marine invertebrates, plus fish, reptiles, mammals and birds, it provides an insight into the existence and way of life of almost everything living in the ocean. Each animal or plant is found in its own particular place and The Marine World encompasses principal ocean habitats and ecosystems including open water, seashores, deep sea, coral reefs and many more. Written with clear, accessible text and illustrated throughout with photographs and detailed drawings, The Marine World provides in depth information to provide answers for each group on 'what?' 'where?' and 'how?', via sections on identification, distribution, structure, biology, classification and conservation.

In this book, geologists Jan Zalasiewicz and Mark Williams consider the deep history of oceans, how and when they may have formed on the young Earth - topics of intense current research - how they became salty, and how they evolved through Earth history.

This title will introduce readers to ocean ecosystems, the plants and animals that thrive there, its climate, its food web, any threats to it, and conservation efforts. Readers will also learn about the most well known oceans and their unique characteristics. . Aligned to Common Core Standards and correlated to state standards.

'Exploring the World Ocean' presents oceanography as a systems science, aimed at understanding the world ocean as a single, interdependent system of interacting geological, physical, chemical and biological processes. Also emphasized is the idea that ocea
