The colourful and graceful mimic octopus boasts some of the most elaborate defensive maneuvers in nature. To confuse both predator and prey alike, it actually twists its semifluid form into the shapes of other sea creatures, changing its colour and behavior accordingly. They have been observed copying seahorses, stingrays, flatfish, sea snakes, jellyfish, squid, starfish, crabs, lionfish, and more. There may yet be unknown transformations as well.
