This mimic octopus (Thaumoctopus mimicus) seems to be blinking at us as it tries to hide in a sandy slope on the north of Bali.
These masters of disguise have their skin full of chromatophores, small cells full of pigment that they can stretch or contract at will. They can do this so fast that they are able to change color in milliseconds! The color change displays of an octopus are certainly one of the most amazing things that you can witness while diving.
But what makes the mimic octopus so special is its ability to mimic other species of marine organisms by changing its shape. It would do this mainly to avoid predators, so it will mimic mainly poisonous organisms like a jellyfish, a lionfish or a sea snake. The mimic octopus is actually the only known living specie that can mimic more than one other species!
