Underwater River of the Day: Professional diver Anatoly Beloshchin snapped these shots of an underwater river at the Angelita cenote near Tulum.

We are 30 meters deep, fresh water, then 60 meters deep – salty water and under me I see a river, island and fallen leaves… Actually, the river, which you can see, is a layer of hydrogen sulphide.

As Redditor penzoilthehippo points out, “This totally explains how there’s a beach in Spongebob Squarepants.”

From Wikipedia:  ”Hydrogen sulfide is considered a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H₂S is comparable with that of hydrogen cyanide. It forms a complex bond with iron in the mitochondrial cytochrome enzymes, thereby blocking oxygen from binding and stopping cellular respiration.”

It’s no wonder Mr. Squarepants is a tad wacky…
