Have you ever seen an underwater waterfall?

Well technically, there cannot be a "waterfall" underwater. Observed only in the southwest coast of Mauritius, this is actually one of the most baffling optical illusion in the whole planet. Mauritius, being a relatively young island, happens to sit on an ocean shelf raised above seabed level. Off this particular coast, a gradual slope is noticed, abruptly ending in a 4000-meter-deep abyss drop, and it is actually sand and slit sediments perpetually falling in a way that makes it look like they’re pouring down a waterfall. It is perfectly safe to swim or surf on this water.
