Cyclostomes are an ancient order of stenolaemate bryozoans ranging back to the Lower Ordovician. Although moderately diverse and locally abundant at the present-day, cyclostomes are invariably outnumbered by cheilostome bryozoans and seldom constitute more than 20% of the species recorded in regional bryozoan faunas.

The zooids are soft bodied organisms with tentacles that live inside a cell that is part of the colony’s exoskeleton. The way these cells are arranged depends on the morphotype of the species. Morphotypes Exercise 8.1 – Marine Paleoenvironments.
