The vast oceans of the world contain some amazing things. One of its most mind-blowing inhabitants is a tiny, solar-powered sea slug that only grows up to 5mm (0.2 inches) long and looks, well, like a cute little cartoon sheep.
The ocean is full of a massive array of undiscovered species, so scientists are always finding new types of creatures lurking offshore. The circle-making pufferfish discovered in 2013 are one great example of a species mankind only recently encountered for the first time.
But you don’t have to take our word for it — the International Institute for Species Exploration (IISE) even included it in their 2015 Top Ten New Species list!
The strange blue creature in the photo above may look like a monster from a Japanese RPG, but is actually a real animal—the Glaucus atlanticus sea slug, to be exact.
Commonly known as the blue dragon or blue sea slug, this beautiful little mollusk can be found off the coast of South Africa, Australia and Mozambique, floating on the surface tension of the water.
Glaucus atlanticus got quite a bit of attention on the internet in April after a stunning up-close photo was posted to imigur (above). While we only just stumbled upon the blue dragon today, the moment we saw it we had the feeling this wasn’t the first time we had seen a sea slug that looked like something out of a fantasy world.
That’s right! I choose you, thecacera pacifica!
Until recently, it was generally believed that the design for Pikachu was based on the mouse.
However, recent Japanese research suggests that Pikachu may have actually been modeled off thecacera pacifica, a species of sea slug found in the Indian and Western Pacific Oceans.
