Octopus swimming

Poetry in motion. Credit: UGA Aquarium

Katherine Courage at Scientific American blogs  has a nice write-up of swimming moves by octopus.  Different species of octopus will move around via jet propulsion or by walking along the sea floor, but some species can move through open water by swimming motions with their tentacles. From the written description, it sounds a bit like the breast stroke.
She has an earlier post describing an octopus-inspired robot which can propel itself using only its appendages.
As I have struggle to coordinate my four appendages into a coherent swimming motion, I do have to bow to these critters, who keep everything going swimmingly.
