Some friends of mine posted some photos of what is commonly thought to be a mimic octopus.

Many confuse this animal with another animal called a Wonderpus, or Wunderpus photogenicus and it is really easy to do so

Below is a photo series that shows a circular series of white markings that are clearly delineated from the surround darker tissue, which are the distinctive markings on a wonderpus. Also, the wonderpus has eyes that tend to be on elevated stalks.
