Octopuses Walk On Two Feet
“WASHINGTON – Octopuses, known for using camouflage to avoid predators, have been observed apparently trying to sneak away by walking on two arms while pretending to be a bunch of algae. Two kinds of octopus were seen to use different ways of walking along the sea floor, researchers were reporting in Friday’s issue of the journal Science.
The movements were discovered by Christine L. Huffard of the University of California, Berkeley, who was studying underwater video camera tapes of the animals.
Berkeley professor Robert J. Full said Huffard was studying octopus movement as part of a robotics project. He said the researchers use examples from nature in designing robots; one project is to build a soft robot.
Octopuses trying to avoid being eaten usually hold still to camouflage themselves. But by walking on two arms, these two types were able to move quickly while using their other arms to disguise themselves.
Two individuals of O. marginatus from Indonesia wrapped six arms around themselves, looking like a coconut on the sea floor. They ten used the two rear arms to move backward.”
This is really interesting. I found it fascinating.
