Of all the mysterious creatures of the deep, few are more intriguing than the giant squid. While the giant squid is admittedly rare, its freaky cousin -- the colossal squid -- is a slightly more common sight on the high seas. Still, both are rare enough that most people believed them to be myths until fairly recently.
New evidence and several live encounters have shattered those beliefs. One of the encounters that changed people's minds was a 2013 run-in between Russian fishermen and a colossal squid. They even managed to film their interaction with the creature.
I know it's not exactly a friendly thought, especially because colossal squid are so rare, but I bet these things would taste great.
