It’s Cephalopod week!  All Cephalopod all the time!

Check this video of a mimic octopus in the wild.

Didja see the Labroides wrasse?

These guys can blend into any environment and become almost invisible.  See if you can spot the Mimic Octopus in this picture:

“I Iz hidden.”

Mimic Octopuses (not Octopi) were discovered about 10 years ago in 1998.  Up until then, they were mis-identified as crabs, algae or sea shells.

Although all species of octopus have the ability to change the color and texture of their skin, and many species can blend in with the sea floor and look like rocks, the mimic octopus is the first octopus species ever observed to impersonate other animals

Based on observation, scientists think that the mimic octopus may decide which animal to impersonate based on which predator happens to be nearby. For example, when the octopus was being attacked by damselfishes, scientists observed that the octopus took on the appearance of the banded sea snake, which is a predator of the damselfish. The octopus impersonates the banded sea snake by turning black and yellow, burying six of its arms, and waving its other two arms in opposite directions, so they look like two banded seas snakes.

Here’s a mimic pretending to be a seasnake:
