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.
Sea stars use their water vascular system, which helps to circulate oxygen throughout their body. Oxygen is absorbed directly from the seawater through their tube feet and then transported to the various tissues and organs. This system allows sea stars to obtain the oxygen they need for respiration.
