Starfish as a species mainly eat meat, though there are a few starfish that do eat rotting plants found on the sea floor. Some starfish focus on detritus --- meaning they eat just about anything that is decomposing. The main diet of starfish are crustaceans i.e. claims, sea snails, oysters, hermit crabs, and other mollusks. Starfish are opportunistic and will eat any slow moving or dieing fish. At times starfish will even eat other starfish.
The ring canals in a starfish are part of its water vascular system, which is crucial for locomotion, feeding, and gas exchange. These canals circulate seawater throughout the starfish's body, allowing it to control the hydraulic pressure in its tube feet. By contracting and relaxing muscles, the starfish can extend or retract its tube feet, enabling movement and the ability to grasp and manipulate objects. Overall, the ring canals play a vital role in the starfish's ability to interact with its environment.
It eats shell fish (mollucs) and will attach to the outside of the shell, and will use it's muscles to open it, and eat what's inside.
