PHDID YOU KNOW? 
The mimic octopus (Thaumoctopus mimicus) has the incredible ability to impersonate other sea creatures.
First discovered in Indonesia in 1998, the mimic octopus (Thaumoctopus mimicus) lives in the shallow waters in the Indo-Pacific. They are relatively small, only about two feet in length, and are pale brown in color with a number of brown and white stripes. Like many other cephalopods, the mimic octopus has color-changing cells, or chromatophores, covering its skin. This allows the animal to quickly change color by expanding or contracting the cells, and ultimately blend into its environment.
But the mimic octopus takes the deception a step further. In addition to just changing its color and texture, the animal will change the way it moves its arms to impersonate a variety of other marine species. It can “mimic” 15 different species (that we know of)!
