Mimic Octopus

As if a testament to this animals extraordinary camouflage and mimic abilities, it was only discovered in 1998. It mimics the physical likeness and movements of more than 15 different species, including sea snakes, lionfish, flatfish, brittle stars, giant crabs, sea shells, stingrays, flounders, jellyfish, sea anemones, and mantis shrimp by contorting its body and arms, and changing colour.

Even more incredible, the mimic may decide which animal to impersonate depending on local predators. For example, when the octopus was being attacked by damselfish, the octopus was observed to appear as a banded sea snake, a damselfish predator. The octopus impersonates the snake by turning black and yellow, burying six of its arms, and waving its other two arms in opposite directions.
