Not all of the darkest, strangest corners of the universe are in some distant galaxy, millions of light-years away.
In fact, the most mysterious of these dark places is right here on Earth.
A place with no sunlight, crushing pressure, and near-freezing temperatures is not the desolate wasteland that one might expect it to be.
It is instead populated with a huge variety of life.
Life that takes shape in ways that our terrestrial minds can barely comprehend.
Some creatures of the deep have enormous piercing eyes.
Others have no eyes at all.
And others still have eyes inside their transparent domed heads.
Others glow for defense or glow for predation.
And at these depths, where photosynthesis cannot occur, the food chain becomes a little unpredictable.
