Invisible animals on the planet


 
 We’ve all heard of squid and octopus using pigments to blend in with their surroundings, but what about becoming completely invisible? To become actually see through, and appear as if you aren’t there, you need to either allow light to travel through you unimpeded, or bend light around you - so that none reflects back at an observer. It’s a tricky task, but some animals are almost there.


In the ocean animals have two choices if they want to hide. Creatures that live in the deep ocean close to the seafloor can blend in with sand or rocks, or hide in coral. In the deep ocean it is often pitch black anyway and predators lack eyes, so being invisible is not necessary.

Animals that live close to the surface and want to hide can produce dazzling displays of light in a process known as bioluminescence, confusing predators below who think they are looking at dappled sunshine hitting the water’s surface. Animals that live in midwater though have neither of these options. This region is known as the pelagic zone, and it also happens to be where most invisible animals live.
Perhaps the easiest way of becoming invisible is by being transparent and letting light travel completely through you. In open oceans, which lack structures to hide behind, being transparent is a great way of hiding from all Viewpoint
