A couple of weeks ago I bought a starfish, which I thought was a sand sifter. Now the strangest thing happend. Today half of his leg came off and it is still moving, the starfish is alive as well. I have seen a starfish regenerate a leg, but I have never seen a leg regenerate a starfish. Does anybody know anything about this? I attached a photo of it.

Many starfish reproduce by dropping legs, then the leg grws into a starfish, however, I thought some part of the disc had to be left on the leg. I am uncertain if the tip of a leg will grow into another starfish, but it is certainly possible.
