Most Anthozoans are carnivores. Prey is captured with mucus or stingers (more about these stingers see cnidarians in general). Tentacles may push larger prey into the central mouth. The edges of the mouth may be inflated into 'lips' that pucker to hold prey as it is swallowed.

How do anthozoa digest food?

They have slit-like mouth openings and a pharynx, which is the muscular part of the digestive system that serves to ingest as well as egest food. It may extend for up to two-thirds the length of the body before opening into the gastrovascular cavity.

What do anthozoa feed on?

They feed on fishes, which are caught by means of the numerous nematocysts in their tentacles. These animals are known for their symbionts. These include species of fish that actually live among the tentacles of large anemones, somehow avoiding lethal contact with the nematocysts.
