Mimic Octopus

  The mimic octopus are a species of octopus with an extremely impressive mimic skill. It is able to copy around seventeen other animals by changing its movement, arm position, texture and color. These animals include lion fish, brittle stars, flounders, sea snakes, giant crabs, jellyfish, sea shells, sea anemones and mantis shrimp. It grows up to 60 centimeters or 2 feet. Its normal coloring is brown with with white stripes or spots. The mimic octopus is the first octopus ever observed to impersonate other animals.
  Based on observation, the mimic octopus decides on what to mimic depending on local predators. For example, when the mimic octopus was attacked a damselfish, it changed to imitate a sea snake, a predator of the damselfish.
  Mimic octopi normally eats small fish, crabs, and worms. Also, mimic octopus also prey on themselves like many other octopi, their bodies are made of soft, nutritious muscle, without spine or armor. Their main predators are barracuda and small sharks.
