What are bryozoans
Fossil bryozoans may not have a symmetrical shape because every specimen is a complete or broken piece of a colony made of many tiny units called zooids (Figure.Bryozoans are made up of colonies of individuals, called zooids. If you look at colonies through a magnifying glass, you can see openings in the geometric patterns they form. It is inside each of those openings that an individual zooid lives. Bryozoan colonies can get very large--containing about two million zooids and stretching a foot or more ...If you have bryozoans in your pond, it is an indicator that you have a healthy ecosystem. Bryozoan feeding habits mean they filter the water as they feed, like oysters in saltwater, helping to consume algae and remove suspended sediments. Due to the flow of water and available food items around the colony, other small animals tend to congregate ...

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.
