Full Fathom 5000 - The Expedition of the HMS Challenger and the Strange Animals It Found in the Deep Sea

This book gives an account of the remarkable discoveries that were made during the 1872-1876 voyage of the HMS Challenger, and it describes the strange and bizarre creatures that live in perpetual darkness a kilometer or more below the surface of the sea. The journey had momentous consequences: not only uncovering a whole vast new range of animals whose existence had never before been suspected but also initiating the systematic exploration of the oceans.
