Bryozoans are a phylum of microscopic, aquatic invertebrates that live in sessile colonies of genetically identical members. The individuals are not autonomous and are termed zooids. They grow as calcified or gelatinous encrusting masses or branching tree-like structures. Having said that, there are notable exceptions, including a genus of ...

Bryozoans. Introduction. The Bryozoa, also known as Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals that resemble corals. They are found in marine, brackish and freshwater habitats. Marine species are common on coral reefs but a few occur in oceanic trenches, and others are found in polar waters.. Corals were a common component of ancient life in Michigan. There are many types of corals or animals that look like corals – like bryozoans (moss-animals) and stromatoporoids (sponges). These animals often live in colonies but sometimes are solitary animals.

Bryozoa. : Life History and Ecology. Bryozoans can reproduce both sexually and asexually. Asexual reproduction occurs by budding off new zooids as the colony grows, and is this the main way by which a colony expands in size. If a piece of a bryozoan colony breaks off, the piece can continue to grow and will form a new colony.

Mollusca. - Most species in the phylum have an open circulatory system. - The coelomic fluid is confined to a small area around the heart. - Their mouth may contain a radula. Mollusca. - Highly segmented body with setae on each segment. - Closed circulatory system. - Ventral nerve cord running down the length of the entire body.

Mar 5, 2020 · The Bryozoans are an ancient phylum of small to microscopic – but fascinating and often beautiful – animals that build intricate colonies. Watching them alive under a microscope is a wonderful experience. They are well preserved in the fossil record because of their zooecia and we know they have been around since the Ordovician era (500 MYA). It is also unclear whether the phylum Bryozoa is a monophyletic group (i.e., whether they include all and only a single ancestor species and all its descendants) because bryozoan evolutionary relationships to other phyla remain inexact. Bryozoans are primarily a marine group ranging from 4,000 to 4,500 recognized species.Bryozoa.
