We kindly referred to him as Rhino! (Rhino starfish). After about two years we gave him back to the LFS, actually about a month ago now. The bugger kept eating my rescue jobs (I try and save dying coral). Basically how it works, he crawls around looking for stuff (dying coral) on his hundred or so itsy bity legs, parks himself smack bang on top, proceeds to remove his stomach and wrap around "the meal" and sits there and slowly digests it. He wouldn't touch anything healthy, a bit like a vulture who couldn't wait. I had some amazing shots (can't find them now) of the really intricate detail of the stomach.
