Is it an alien from the depths of space, riding the solar storms or living in subspace? Or perhaps a super-creepy Alien face hugger from Prometheus? Just take a gander at that scary-looking tail, ready to wrap around your neck and implant that egg.
Nope, while it may look otherworldly, it's actually a gorgeous X-ray of a stingray, a newly discovered species in fact. Meet the "pancake" stingray, recently found in the Amazon. It's one of two new rays, named Heliotrygon gomesi and Heliotrygon rosai (catchy, hey?), and while it looks pretty damn cool on the inside, it's a bit more mundane and brown on the outside.
Still, it goes to show that we still haven't discovered all forms of life on our own planet, let alone Martians. Apparently we know more about the surface of other planets than we do about our oceans, no wonder NASA trains under water. [OurAmazingPlanet via Reddit BuzzFeed]
