What system in starfishes bodies help them catch and hold their food?

Their sucker feet hold on to an animal as they extrude their stomach, eat the food, digest, then bring their stomachs back in to their body.

I was just doing a lab report about a sea star dissection and we had to answer this question- I hope that you didn't need this for the same type of lab report because dissecting the sea stars was pretty disgusting! Hope I helped!
