Video shows octopus plays tug of war with underwater robot to defend a cable

If a giant robotic arm swooped in to destroy your home, you would probably be pretty angry. So it is hardly surprising that an octopus living off the Canadian coast in the Pacific Ocean jumped to the defence of the coil of cable it had been living under when a robot came to take it away. A video captured while the underwater robot tried to carry out maintenance work, shows the cephalopod playing tug of war with the robotic arm. The dispute was filmed by Nautilus Live while engineers were using a submarine's robotic arm to repair a cable which was part of the Ocean Networks Canada underwater observatory. Sadly, the fight was only going to end one way, and despite the octopuses valiant efforts to protect its home by hanging onto cord holding the cable coil together, it ultimately lost.
