Sunflower seastars are quick, efficient hunters, moving at an astonishing speed of 1m/min (3.3ft/min) using 15,000 tube feet which lie on the undersides of their bodies. They are commonly found around urchin barrens, as the sea urchin is a favorite food. They also eat clams, snails, abalone, sea cucumbers and other sea stars. In Monterey Bay, California, they will feed on dead or dying squid.

Although the sunflower seastar can greatly extend its mouth, for larger prey, the stomach can extend outside the mouth to digest prey, such as gastropods like abalone.
Easily stressed by predators such as large fish and other sea stars, they can shed arms to escape, which will grow back within a few weeks. They are preyed upon by the king crab.

Not really, mainly starfish prey prefer shelled animals such as oysters and clams. They would not eat starfish because to feed they tend to push open shells using their tube feet and extend their stomach out to engulf and digest food. Starfish have a rough surface and starfish prefer soft tissue as a food.
I wouldn't think so. In the wild starfish eat mussels and other molluscs.
No, starfish do not eat with their mouths. Instead, they turn their stomach inside out to grab and partially digest the food they want to eat.
No studies have gone into this, but you can say that starfish send their stomach and other digestive fluids out from their body to digest the food that they will eat, then the starfish will eat the partially digested food back up. So, it is sort of regurgitating.
Most starfish eat clam, oysters, and mussels. There are a few species that eat sponges, plankton and coral. There are even some species that will go outside of the water to find decomposing plants and animals.
