Despite our planet's name, Earth, most of it is under water. Thirty major groups of animals live on the planet, 19 of which live exclusively in the sea. This book takes the reader on a voyage of discovery in an imaginary "mini-sub" which travels through the "twilight zone" and slides down the continental slope to a vast abyssal plain. It introduces giant sea spiders, sneaky sea squirts, and worms making "fairy rings". At a mid-ocean ridge, molten lava melts the Earth's crust and hot-water spouts are home to amazing animals. The "mini-sub" visits rocky slopes of underwater volcanoes with soft corals and shoals of brightly coloured fish. Finally, it makes a difficult and dangerous dive to the deepest place on Earth, the Mariana Trench. This book is part of a series of illustrated science texts for children, teenagers and families. The authors are scientists who are prominent in their fields and have an interest in furthering the public understanding of science.
