Bryozoa are an incredibly diverse group of metazoans with a geological record extending from Early Ordovician to Recent. There are more than 6000 extant species and probably 2-3 times that number of fossil species.Bryozoans are very small, colonial animals. In mass, they combine to form mats, mounds, branches, fans, or lacy fronds. Tentacles surrounding their mouths grabbed microscopic organisms floating in the water. These animals differ from coral in that they lived in pits on the surface of the structure and not in radiating partitioned cups.
