Dive into the unexplored depths of the deep blue sea and discover its secrets with this trusty and beautifully-illustrated guide by Lonely Planet Kids. Meet the amazing animals, birds and plants that live in our oceans, the habitats in which they live, then learn about the harmful effects climate change, oil spills and plastic waste can have on them - plus, what you can do to help future generations! From the odd-shaped head of the great hammerhead shark to the hairy strips of baleen in a baleen whale's mouth, meet some of the ocean's oddest creatures and discover how they have evolved to live and thrive under the sea. Journey from the colourful coral reefs of the Indian Ocean to the wild waves of freezing Antarctica, covering everywhere from sandy beaches, deserted open seas and mile-deep trenches in-between. Learn all about the history of how the oceans came to be, as well as the sunken cities that were claimed by them, then understand just how powerful the force of water can be as you explore tides, waves, tsunamis and currents. After dropping anchor like the pirate Jack Sparrow on tropical, palm-fringed islands, end with a lesson on how humans have been using and abusing our oceans throughout the years, and what we can do to help protect them for the future.
