If you thought only Harry Potter was lucky enough to possess the cloak of invisibility, you clearly missed out Cystisoma – a creature that lives underwater and has the ability to go completely transparent in front of its predators.
These majestic creatures have antireflective coatings that help them in blending into the deep sea without being discovered by the higher members in the food chain. The deep ocean isn’t a safe place for tiny creatures that cannot cross over 7-inches in size and Cystisoma species know it better than anyone else. But their life isn’t as easy as it sounds; their eyes are a major giveaway. The retina in their eyes is pigmented therefore their eyes cannot be invisible like the other parts of a Cystisoma’s body.
