The main structures that are used for feeding are the endostyle with mucous glands, the peripharyngeal grooves and dorsal grooves lined with cilia, the stigmata, and the esophagus. the tunicates excrete a mucus film to capture prey that has been sucked in with the water. This mucus is secreted by the endostyle continuously which is then moved by cilia into the brachial basket, to the dorsal groove, and finally to the esophagus .
