Walking octopus

Theories that walking requires hard bones and skeletal muscle are discredited, as octopuses have neither.

[They] can tuck up six of their arms while running on the other two, U.S. researchers reported on Thursday.

They can use their other six arms to disguise themselves from predators, either as rolling coconuts or clumps of floating algae.

The behaviour has been captured on video.
