I always thought, a feather star is like any other feather star. But when I looked into my books I realized, there are several different species. This is a Prickly feather star (Stephanometra echinus). Look here for more photos of feather stars.
Take a good look. Sometimes there are symbiotic shrimps, squat lobsters or clingfish inside the stars. And if you are lucky, there might be a ghostpipefish living very close by.
