Life on the edge of a frozen sea is tough. Ice at both poles is constantly moving, and in winter freezes solid with air temperatures 70°C below freezing. Only in spring, with the retreating ice and light reaching the water, does life begin again. Written by Anonymous

Endless blue stretches in every direction. The sea bed is a staggering eight kilometers deeper down and the nearest island is 500 kilometers away. There is nothing save the burning sun above and the blackened abyss below. How, then, does life exist? Written by Anonymous

The deep sea, which gets darker till no more sunlight penetrates at about a kilometer depth, and ever colder closer to the bottom of the ocean, covers most of the planet and is thus by far the largest habitat on earth, yet has been explored less then space, so most scientific expeditions, at some depth requiring modern submarine technology, discover at least one new species, or even whole new branches of submarine life. Like everywhere else, evolution has over millions of years produced several amazing adaptations to even the most extreme conditions, here especially to the lack of sunlight, with its problems for procreation, searching food and fleeing hunters, such as photophore cells which produce specific light types, mimic rare light penetrating from above, etcetera.
