Very little is known about them to this day. In June, a NOAA expedition captured the first footage of a giant squid in American waters.
It comes over 150 years since the first scientific documenting of them. The gargantuan creature can grow up to 40 feet long and live in a world devoid of sunlight.
Most of what is known about them is taken from their floating carcasses, or from the belly of sperm whales.
Giant squid are filled with ammonium ions, which are lighter than seawater, causing them to float after they die.
