We don’t often look for evidence of extraterrestrial life at the bottom of the ocean, but if aliens did want to hide their existence from us you have to admit that the ocean would be a very good place to do it.
That’s why when researchers find something like this on the ocean floor, we instinctively start to think that it might be the work of aliens!
Take this beautiful, odd-looking geometric pattern on the ocean floor, for example. It was found off the coast of Japan’s Amami-Ōshima Island.
The pattern is made of sculpted sand, but it wasn’t made by a human. If that’s the case, then who (or what) put it there?
Unfortunately, it isn’t the work of aliens. The artists behind these odd sand sculptures are actually male puffer fish.
They create these patterns to attract mates.
It’s a big effort for these little fish, especially since they sculpt them using their bodies. Circled in red is a fish working on his masterpiece.

Okay, nature, you win this time. I really expected these patterns to have been made by something creepy, but the puffer fish is a decidedly cute creature.
