How do starfish eat?

Question

I read on a website that they spit their stomachs out at eat through that but that they also feed with the underside of their legs. How would they do that? Are they like taste buds?

Answer 1

It's sort of both.  The sea star's mouth is on the same side as its tube feet.

Sea stars use their tube feet to grip onto potential prey, but they don't eat with their feet.  If a sea star is getting ready to eat a mussel, it uses its tube feet to pry open the mussel shell just enough that it can evert its stomach out through its mouth and into the mussel.  The sea star then secretes digestive juices into the open mussel shell, essentially liquifying the mussel.  Then the sea star uses its stomach (which is partially inside of the mussel) to absorb the partially digested mussel tissues.

Answer 2

They eject thier stomachs onto thier food and the stomach acids dissolve the food and then they eat it
