Operculum (bryozoa)
text:
In the bryozoan order Cheilostomatida, the operculum is a calcareous or chitinous lid-like structure that protects the opening through which the polypide protrudes. Many species have modified the operculum in specialized zooids (avicularia) to form a range of mandibles or hair-like setae. The cyclostome family Eleidae also convergently evolved an opercular structure during the Early Cretaceous to Paleocene.
