What do starfish eat?

What kind of food does the Choriaster granulatus eat?
Choriaster granulatus is a carnivore and has its mouth on the underside of its body, like other sea stars. Their prey is absorbed outside their mouths by forcing out their digestive organs from their stomach. Its prey include carrion and small invertebrates such as coral polyps.
Why are the arms of Choriaster granulatus deformed?
The arms of Choriaster granulatus can become deformed when small parasitic limpets attach to the underside of the arms. There is also the threat of habitat loss, due to ocean acidification which leads to coral bleaching. ^ C.L. Mah (2010).
Where does a Choriaster granulatus starfish live?
