The coral unit is the polyp while the bryozoan unit is the zooid. Both have tentacles used to capture prey and their bodies are permanently fixed to the colony mass, i.e. sessile. Both coral polyps and bryozoan zooids are able to extend from and contract within the colony matrix.The coral unit is the polyp while the bryozoan unit is the zooid.
