The Walking Octopus

From Site:
This is the extraordinary behaviour observed for the first time in two species of octopus.
The two species have slightly different strategies. Octopus marginatus from Indonesia wraps itself into a ball while walking, perhaps to imitate a coconut rolling with the current.
Tiny Octopus aculeatus of Australia holds up six of its arms to disguise itself as a clump of seaweed, while walking at up to 14 centimetres per second - faster than it can manage using more than two arms.
