Addendum: Eight arms to hold you.
Just came across this article on an anigmatic new taxon from the Ediacaran, reporting the discovery of the eight-armed organism Eoandromeda octobrachiata from China and Australia. The article isn't very well written, but it's a gorgeous little beastie. You can also read the abstract from the actual paper in Geology (in which the creature was described) here.
