The mimic octopus (Thaumoctopus mimicus) is a species of octopus from the Indo-Pacific region. Like other octopuses, it uses its chromatophores to disguise itself. It is noteworthy for being able to impersonate a wide variety of other marine animals. While many animals mimic either their environment or other animals to avoid predation, the mimic octopus and its close relative the wunderpus are the only ones known to actively imitate several animals in order to elude predators.
