Tonight when I got home after a long day at the beach I found my brittle star fish dead missing all five tentacles and all ripped apart. So my question is who is the brutal murderer of this inocent brittle starfish? The suspects are the following: A) The sea urchin. B) The hummelincki octopus. C) The red serpent starfish (which was found right next to the body). D) Myself for not taking good care of the brittle starfish. Please post you expert advise.
