Initially, if you happened upon a Mimic octopus, you would think that it was just a normal, slightly small, octopus. But the Mimic octopus is not your typical octopus. These sea creatures have LOTS of tricks up their sleeve.
It is the behavior of the Mimic octopus that makes it stand out and gives it it’s name. “Mimicry is commonly used as a survival strategy in nature. However the mimic appears to be able to take on the appearance of not just 1 other species, but of several.” Not only that, but all of the other species that the Mimic imitates are venomous, making this a deliberate and evolved tactic of survival.
The Mimic octopus can make itself appear to be a Lion fish, sea snake and a sole/flatfish. It bends and shapes it’s body to look just like theirs. Below is a video showing the Mimic octopus in action.
The Mimic octopus also has a lot of the same physical characteristics of other octopus species have. They have the ability to change the color and texture of their skin to blend into their surroundings to protect themselves. They have “8 arms, a mantle containing 3 hearts and other internal organs, and a siphon used for jet propulsion. The arms have 2 rows of suckers, each sucker having a touch sensor and a chemoreceptor, allowing the mimic effectively to feel and taste its food before it eats it. It has a large brain but lacks the sense of hearing.”
