Illustrated Glossary of Sea Anemone Anatomy - Actinopharynx

This page contains images of sea anemone actinopharynxes. The actinopharynx is the tube leading from the anemone's mouth into the body cavity. The actinopharynx of some anemones contains one or two siphonoglyphs, which are smooth grooves running down the interior of the actinopharynx.
