This colony of a lacy crust bryozoan ( Membranipora membranacea) started off as just a single larva drifting in the waves that eventually settled down on a piece of kelp. From there, it budded duplicates of itself in rows, forming a colony. Lacy crust bryozoans can form large colonies covering an entire kelp blade.About Bryozoan Fossils. We also find Paleozoic Era bryozoan fossils on the beach. They earned the common name, lace corals, due to their delicately threaded appearance, but they were not true corals.

The zooids are usually about 1 mm long and are often rectangular or box-shaped.For example, a previously classified group of animals called lophophorates, which included brachiopods and bryozoans, were long-thought to be primitive deuterostomes. Extensive molecular analysis using rRNA data found these animals are actually protostomes, more closely related to annelids and mollusks. This discovery allowed for the ...

Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves. Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments. Each animal in the colony is called a zooid.They have tentacles with nematocyst or stinging cells. The building unit of a bryozoan colony is usually termed a zooid. The building unit of a coral colony is usually termed a polyp. They are hermaphrodites. They can be both hermaphroditic and gonochoristic (unisexual). Bryozoans are complex and advanced corals with a mouth and anus.Moss Animals (ToL: Bryozoa<Lophotrochozoa<Bilateria<Metazoa<Eukaryota) Bryozoans.
