Many want to feel what it is like to fly in the cosmos—how one’s body levitates in dark space. Personally, I have never been in space, but I have found this feeling on night dives.

In many science fiction movies today—those with alien spaceships—the aliens look very similar to some of the underwater inhabitants of our own planet. Indeed, there is no need to invent some mythical creature to stir up the imagination of the viewer; it is enough just to show an image of a jellyfish, an octopus or a giant crab. And this story is all about the king crabs. There is no need to make deep dives, requiring special training and techniques, to see these aliens underwater. All you need is a little luck and to be in the right place at the right time.
