That's a great question. Around here, they are called starfish and scientists call classify them as echinoderms not fish. There's a great wikipedia site on sea stars (super cool pictures): http://en.wikipedia.org/wiki/Starfish but it doesn't answer your question. This website states they breathe throught their feet: http://www.conservapedia.com/Starfish Interestingly, they have no brain.
