A gastrovascular cavity (which functions as a stomach) with a single opening to the outside is both a mouth and anus. Waste and undigested matter is excreted through this opening, which can be described as an incomplete gut.
The sea anemone has an oral disk, which the organism uses to capture prey. The anemone attaches to the substrate using the basal disk at its posterior end.

Sea anemones are a group of water-dwelling, predatory animals of the order Actiniaria. They are named for the anemone, a terrestrial flower.
