Fenestella reteporata
The bryozoan shown in the image, Fenestella, was fan-shaped. © Great Barrier Reef Marine Park Authority This living Reteporellina bryozoan colony looks very similar to Fenestella, with delicate branching fronds. |
What are bryozoans?
Bryozoans, or ‘moss-animals’ are colonial animals which are common in shallow seawater. They build colony skeletons of calcium carbonate. Although the individual animals are very tiny, they are quite complex with nervous systems and feeding organs. The colonies can be fan-shaped or branching, or can encrust other organisms such as seaweed.
