Byrozoans
Cyclostomatida, or cyclostomata (also known as cyclostomes), are an ancient order of stenolaemate bryozoans which first appeared in the Lower Ordovician. It consists of 7+ suborders, 59+ families, 373+ genera, and 666+ species.The cyclostome bryozoans were dominant in the Mesozoic; since that era, they have decreased.Currently, cyclostomes …14 nov 2017 ...

Another 15,000 species are known only from fossils. As with brachiopods and phoronids, bryozoans possess a peculiar ring of ciliated tentacles, called a lophophore, for collecting food particles suspended in the water.

Colonial and Sessile ...Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Caprellidae. Caprellidae is a family of amphipods commonly known as skeleton shrimps. Their common name denotes the threadlike slender body which allows them to virtually disappear among the fine filaments of seaweed, hydroids and bryozoans. They are sometimes also known as ghost shrimps.

Bryozoan fossils occur in many forms, including finger-shaped, fan-shaped, mats, spiralling fans, and massive irregular mounds. Many of the fossils, if examined closely with a magnifying glass, will show the individual …Bryozoans in the Greenland Sea. Bryozoa is a phylum of small aquatic invertebrates that filter feed with tentacles lined with cilia. Most species are marine and live in tropical seas, although many are in temperate or cold seas, and some live in brackish or freshwater. Of the ~ 4000 extant species, all but one genus is colonial. Bryozoans can form colonies on a variety of different surfaces, from rocks to sandy sediments to the hulls of ships! Scientists have found bryozoans at depths of up to 8,200 metres but the majority live in much shallower waters. Most of the species that live off the coast of New Zealand are found on the mid-continental shelf, between 60–90 ...
Bryozoans. Bryozoans (“moss animals”) act as filter feeders that sieve food particles out of the water. They can live as fans or branching twigs and are important components in forming reefs. Fossils of these organisms are found embedded in shales or dolomite rock rather than as single fossil segments. Chain Coral (Halysites)Gelatinous balls, moss animals and Bryozoans. During the late months of summer, gelatinous balls of various size are commonly seen in ponds and streams in Minnesota. These balls are usually attached to objects such as dock pilings or rocks.
