Of all the ocean habitats the deep ocean remains the least known.
Sixty percent of the earth’s surface is covered by seas more than a mile deep but only a handful of submarines are capable of diving that deep.
We take a journey from the surface right down to the very bottom of the sea and its deepest abyss. The Deep is a place of mountain ranges, perpetual night, pressure extremes and cold and the wierdest life forms on our planet.
Fish with grotesquely cavernous mouths and cruel teeth lurk one kilometer below the surface. Any light is living light, but a glow in the dark may be meant to attract the opposite sex unless it is the deep-sea angler fish who already has her mate conveniently fused to the end of her nose.
On the floor of the ocean deep, all manner of primitive creatures crawl across the ooze.
