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. These organisms superficially resemble cnidarian hydroids and bryozoans (phylum Bryozoa), with the main body consisting of a cup-like calyx that bears a ring of 6 to 36 ciliated tentacles, attached on its dorsal surface to the substrate (or stolon in colonial species) by a long, thin stalk. The calyx and stalk are covered by a thin, collagenous ...General Invasion History: Pectinatella magnifica is a freshwater bryozoan described by Joseph Leidy in 1851 from the Delaware River in the vicinity of Philadelphia. It is widespread in Eastern North America from New Brunswick and Ontario (Ricciardi and Reiswig 1994) to Louisiana and Texas (Everitt 1975). Phylum Bryozoa, Class Gymnolaemata, Order Ctenostomatida, Family Vesiculariidae. Tiny tubular zooids (<0.5 mm tall) interconnected by basal stolons, growing on algae or as minute branching colonies. Appears as a white fuzz or a very delicate hydroid to unaided eye. Common but inconspicuous; especially on wharf pilings & other fouling communities.
There are approximately 4,000 species in the phylum Bryozoa, making it one of the major phyla. Colony forms vary among the different species, ranging from flat, encrusted sheets to folded, leaflike bushes.Characteristics: Bryozoans, also known as moss animals, are colonial, with the expeption of a single genus. Many colonies form sheets covering rocky bottoms or algae, they are called encrusting bryozoans. Others build bush-like structures resembling small corals. They are hermaphrodites, they change sex during their life span.moss animal. Moss animal - Colonial, Filter-Feeders, Habitats: Colonies in extant bryozoans are not just aggregations of zooids but whole organisms having an integrated physiology and behavior that appear to be coordinated to some extent.

Extinction of two bryozoan orders at the end of Permian. The 2nd or 3rd most common fossil group during the Ordovician, after brachiopods. Phylum Bryozoa: Called the "moss-animals" this is the only large phylum of animals that are wholly colonial. Bryozoans produce a covering made of calcium carbonate, chitenous material, or mucous from which the individuals extend their lophophores for feeding. The colonies resemble and are easily confused with sessile hydroids. ….

Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals), are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Most marine species live in …Bryozoa is thus a promising source for cytotoxic/anticancer agents, as well as antibiotics. Their active compounds have been covered in a series of reviews by Blunt et al. (e.g., [ 123 ]) in the journal Natural Product Reports , highlighting the trend of minimal MNP research efforts on this phylum so far.Bryozoa is a phylum of usually sedentary colonial marine invertebrates. Colony morphologies are diverse, typically encrusting or branching, many of them calcified. In all species, the majority or totality of the colony is composed of (typically) box- or cylinder-shaped "autozooids," which feed, providing nourishment for the colony.
