Bryozoans characteristics.
Animals without a backbone are known as invertebrates. Those with a backbone are called vertebrates. About 97% of animals are invertebrates. All major animal groups have representatives in the marine community.
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.

This idea was first suggested by Becklemishev , who proposed, based on characteristics of metamorphosis, that phoronids and bryozoans belong to a group that he named the Podaxonia.Amathia verticillata. Amathia verticillata, commonly known as the spaghetti bryozoan, is a species of colonial bryozoans with a bush-like structure. It is found in shallow temperate and warm waters in the western Atlantic Ocean and the Caribbean Sea and has spread worldwide as a fouling organism. It is regarded as an invasive species in some ... Encrusting bryozoans form flat sheets that spread out over rocks, shells, and other substrates. Forms that grow upwards into the water column may be massive (solid), foliaceous (sheetlike, with zooids on both sides), dendroid (branchlike or treelike), or fenestrate (many branches joining and rejoining to form a netlike or "windowed" shape).Verified answer. biology.

The colonies of different species take different forms, building exoskeletons (outer protective structures) …Bryozoa. Bryozoans, also known as the Polyzoa, Ectoprocta or moss animals, are a phylum of small aquatic animals living in colonies. The colonies usually have a skeleton of calcium carbonate. Bryozoans have a long fossil history, starting in the Ordovician. In their life-style they resemble the polyps which form coral. Bryozoans are also significant biofouling organisms that often interfere with the function of irrigation, water treatment, and industrial cooling systems (Wood, 2005b). The phylum Entoprocta is sometimes grouped with the phylum Ectoprocta (Bryozoa) because of certain similarities; but because these are superficial, this group is discussed in ...Abstract. Lophotrochozoa is a protostome clade that includes disparate animals such as molluscs, annelids, bryozoans, and flatworms, giving it the distinction of including the most body plans of any of the three major clades of Bilateria.

Experiments have shown that some corals, at least, if you lower the pH in which they live, they thrive just fine. They live, they grow, they reproduce – they just don’t make a skeleton.

Bryozoans are tiny, structurally complex organisms that live in colonies made up of modular, skeletonized living chambers called zooids. These microscopic homes allow their inhabitants to pop out to feed on plankton and then retreat if danger threatens. Within a single colony, multiple types of zooids may occur.
