The Cyclostomata are the only extant representatives of the class Stenolaemata, an ancient group of exclusively marine bryozoans. Previous cladistic analyses of cyclostome bryozoans, based exclusively on skeletal characters, revealed extensive homoplasy amongst morphological traits.Bryozoans, sometimes referred to as "moss animals," are a type of simple colonial animal that mostly lives in marine environments (a few inhabit freshwater). Bryozoans feed by means of a lophophore, a small ring of tentacles covered with tiny cilia that are used to filter food from the water. Bryozoan colonies are protected with a covering of organic materials …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.The lophophore is circular with 8-30 tentacles. Further, for this class an important characteristic is polymorphism, consisting of zooids developing in linear ..."A growing number of Cambrian fossils… display characteristics that might be reconciled with a bryozoan affinity – but on the basis of presently available material, no taxon can be interpreted with sufficient certainty to document a pre-Ordovician origin of Bryozoa," write the researchers in their published paper.Many animals possess plantlike characteristics, such as a lack of mobility (e.g., sponges) or the presence of a plantlike growth form (e.g., some corals and bryozoans), but in general such animals lack other plant characteristics. Some past classification systems (see taxonomy) ...Bryozoans are filter feeding invertebrates and can be found in both freshwater and marine habitats, where they are often easy to miss because of their small size and cryptic lifestyle (e.g., encrusting seashells, rocks, or kelp).bryozoan: [noun] any of a phylum (Bryozoa) of aquatic mostly marine invertebrate animals that reproduce by budding and usually form permanently attached branched or mossy colonies.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.

Cyclostomes are an ancient order of stenolaemate bryozoans ranging back to the Lower Ordovician. Although moderately diverse and locally abundant at the present-day, cyclostomes are invariably outnumbered by cheilostome bryozoans and seldom constitute more than 20% of the species recorded in regional bryozoan faunas.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.. Bryozoans are tiny colonial animals. Sometimes called moss animals, there are thousands of species living today.See full list on britannica.com Distinguishing features.

For bryozoan colonies of the cryptic species ...Brachiopods and molluscs are lophotrochozoans with hard external shells which are often believed to have evolved convergently. While palaeontological data indicate that both groups are descended from biomineralising Cambrian ancestors, the closest relatives of brachiopods, phoronids and bryozoans, are mineralised to a much lower extent and are comparatively poorly represented in the ...So bryozoans are important in a kind of ecosystem way. 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. They turn into a jelly instead of a reef. Whether people want to go snorkel on coral jellies is an ....
