Top 7 Most Mind-Blowing Creatures of the Deep
More than 70% of the Earth's surface is covered by water. Our planet is coated with 1.3 billion cubic kilometers of the stuff, the majority of which resides in our oceans at an average depth of nearly four kilometres. The oceans provide us with food and water, power our weather, regulate our climate, and perform countless other functions without which life on Earth would quite simply not exist. If we were being accurate, we would better call our planet not Earth but Water.
Despite its importance, we know a staggeringly small amount about what lives beneath the waves on our tiny blue planet. We have better maps of the Moon and the surface of Mars than we do of our own sea-bed. Currently there exist only five deep-ocean submersibles capable of reaching the 'abyssal plain' that covers more than half of the Earth's surface, and they each cost about $25,000 a day to operate. As a result, humans may have scrutinised 'perhaps a millionth or a billionth of the sea's darkness. Maybe less. Maybe much less.'
With that sobering thought in mind, we cannot begin to imagine what fantastic creatures might lie beneath the waves, awaiting discovery. For all we know, our oceans could be teeming with stranger and more wonderful beasts than anything we have yet laid eyes on. If the following seven animals are anything to go by, what lies beneath the unexplored deep must be truly mind-blowing.
