'Under the Sea' is a part of 'Discoveries', a dynamic new reference series for children. Atmospheric illustrations, strong photographs and lively text engage and encourage readers to discover for themselves the world around them. Titles from Natural History, Our World, Science and Technology and Our Past cover an exciting span of subjects: from the depths of space in 'Stars and Planets' to the inside intricacies of machines in' How Things Work'. A four-page foldout in each title reveals a dramatic, and perhaps unexpected, perspective.
