While carrying out some maintenance work off the Canadian coast in the northern Pacific Ocean, scientists aboard the ocean research vessel Nautilus found themselves squaring off with a small octopus.

As you can see, the octopus does not want to let the robotic arm get the rope ! Note that the team assured no tentacle were armed during the “struggle”.
