The fauna of the deep sea

"The Fauna of the Deep Sea" by Sydney J. Hickson is a scientific book that shines a light on the hidden world of animals living far below the ocean's surface. The book dives into the different kinds of creatures found in the deep sea and the harsh environments they call home. Hickson looks at how these organisms have changed over time to survive in such extreme places. The book kicks off by talking about how people used to think the deep ocean was empty of life—a thought that was proven wrong. Then he points to the important research trips, like the one by the H.M.S. Challenger, that uncovered the fantastic array of life in the deep sea. With this introduction, the book then prepares to go further into what deep-sea organisms are like, what their environment is like, and where they came from, laying the groundwork for more detailed talks later on.
