Down Down Down: A Journey to the Bottom of the Sea by Steve Jenkins
 * Viewed from space, the earth looks like a water blue ball.
 * Oceans cover more than two thirdsofthe globe's surface, and well over half the planet lies beneath water more than a mile deep.
 * More humans ave walked on the moon than have visited the deepest spot in the sea.
 * It's calm now but during a storm powerful winds can churn the surface into mountainous waves.
 * They may be pursuing prey, escaping danger or sending a message to others of their kind.
 * They themselves are food for billions of animals.
 * The sunlight is already beginning to fade. The pressure is increasing.
 * We are about as deep as most humans can dive without scuba gear.
 * Life flourishes here.
 * Not all are fast swimming hunters.
 * Unlike air, water and other fluids don't compress much, or get smaller, under pressure.
 * They rise from the depths at night to feed, returning to safety at dawn.
 * Animals also use light to attract a mate or send messages to one another.
 * Not even the faintest sunlight can reach us here.
 * It's getting colder and the pressure is enormous.
 * The hunter, lit up with glowing gunk and unable to hide, is likely to become a victim itself.
 * Soon his body will fuse to hers.
 * There he will remain, living off the female's body for the rest of his life.
 * Some hunters have a stomach that can stretch to many times its normal size, allowing them to swallow an animal that is larger than they are.
 * We have arrived at a flat, nearly featureless surface.
 * First we'll investigate what looks like a city of smoking towers...
 * It's even possible that life on our planet began in a place like this.
 * The descent took five hours, but the men stayed on the bottom for only twenty minutes.
 * Unmanned probes have explored the Challenger Deep on a few other occasions, but it is still one of the most remote places on earth.
 * Some scientists believe that we've seen fewer than half the large animals living in the sea.
 * These tentacles can give human swimmers painful, even fatal stings.
 * They can soar for hours at a time without flapping their wings.
 * They also have some 3,000 razor sharp teeth, arranged in rows.
 * It can however raise its body temperature. This allows its muscles to work at full power even in cold water.
