    Any star fish with knobs on have mouths like mills.

    I don't know that particular one. But it does have knobs so it is most likely not reef safe.

    The mouths of starfish are often referd to as the gastric mill. This means that they process and grind away at corals with devastation. I will check up for you on this particular starfish.
