Animals In The Depths Of The Sea

The deep sea, which has been immersed in total darkness since the dawn of time, occupies 85% of ocean space, forming the planet's largest habitat. Yet these depths abound with mystery. The deep sea is mostly uncharted - only about 5 percent of the seafloor has been mapped with any reasonable degree of detail - and we know very little about the creatures that call it home.

Current estimates about the number of species yet to be found vary between ten and thirty million. The deep sea is without doubt Earth's largest reservoir of life.
