Kraken, the mythical sea beast, is real.
Giant squids live in the dark depths of the ocean and, to this day, very little is known about them.
Most of what the world has learned about the gargantuan creature, which can grow up to 40 feet and live in a world devoid of sunlight, is taken from their floating carcasses or from the belly of sperm
By 2005 no scientist has ever shot giant squid alive. One was not filmed until 2013. But scientists believe there are millions of them.
In June, the NOAA Ocean Exploration and Research Expedition captured the first shots of giant squid in American waters.
David Grann of New York writes that giant squid can be "bigger than a whale and stronger than an elephant, with a beak that can tear steel cables."
Here is what is known about the mysterious beast and why so many are still unknown.
