shapeshifters
are to real there's many on earth
shapeshifting can be very basic like just changing ones vibration or skin tone
also i heard from 2 differnet source so far that there's this other kind of ocotups even more advanced then this 1 that can even mimic human speech!
this another 1 The mimic octopus (Thaumoctopus mimicus) was discovered in 1998 in the waters off Sulawesi, Indonesia. Its habitat consists of shallow, open, sandy plains with minimal reef and coral cover. Unfortunately, this leaves the tiny octopus vulnerable to predators.
Despite its vulnerability, Mystique from the X-Men has nothing on this octopus! This master of camouflage can change color to disguise itself into the reefs surrounding it. It can also imitate many different species of underwater life by shapeshifting. This unique octopus can impersonate a diverse range of species—at least 13 have been recorded so far—including lionfish, sea snakes, jellyfish, and sea anemones.
Most of the impersonated species are poisonous, giving the mimic octopus protection from predators, but it is also known to imitate members of the opposite sex in crabs, luring them in before feasting on them.
