This is a crinoid, a cousin to sea urchins, sea cucumbers and starfish. I suppose some of them have stalks like sea anemones, but these ones don’t! The image is from The Unstalked Crinoids of the Siboga Expedition gallery in the Biodiversity Heritage Library’s Flickr account, which is all taken from this book of the same name.
