Colony of bryozoans. Things To Know About Colony of bryozoans.

Bryozoans are microscopic aquatic invertebrates that live in colonies. The colonies of different species take different forms, building exoskeletons (outer protective structures) …Bryozoans are tiny animals, no larger than 4 millimeters (5/32 of an inch) wide. They float alone for a time, but eventually form colonies, working together for mutual benefit. In this way, they are much like coral. But coral builds strong, sturdy structures that last long after the animals they house have died.5. Like many corals, bryozoans ("moss animals") are colonial, but the individuals making up the colony are very small. Bryozoans are still alive today, and close examination reveals that each individual has a lophophore. Thus, in spite of their coral-like appearance, they are more closely related to the brachiopods. A.The oldest fossils of bryozoans, colonies made of tiny individual animals called zooids, were previously dated to the Ordovician period around 480 million years ago. This is about 50 million years later than most other animal groups first emerged.

If you ever find one, and have a magnifying glass handy, a closer look of a bryozoan colony can be an eye-opening, and unique, experience.

Bryozoans can reproduce sexually or asexually through budding and fission, and individual zooids are hermaphroditic. Statoblasts (Fig. 10.9C), the small, resistant structures of the Ectoprocta that are formed through budding, are important for dispersal and surviving harsh conditions.
