Animals

Every day we seem to get news that disregards previous rules about our existence, proving that life is possible even in the most unexpected places. While that feels like something Gandalf might say, it's actually true; we recently learned that 90% of the planet's carbon is beneath the surface, where a biosphere twice that of our oceans exists. Who even knows what lives there? We've also learned about tiny creatures who can live in the deepest, darkest parts of the oceans as well as in volcanoes, so maybe it's not as surprising to find out that some fish can actually live in dead zones.
