Bryozoa

Bryozoa, also known as Ectoprocta, is a group of aquatic invertebrates that are generally found in marine and freshwater environments. They are considered to be one of the most diverse and successful groups of aquatic animals, having adapted to a wide range of habitats and environmental conditions. Bryozoans are generally small in size (less than 1mm to several centimeters) and typically form colonies of individual zooids that are connected by an extracellular matrix. They feed by filtering organic material from the water and produce mucous-like filaments to capture food particles. Bryozoans are important components of aquatic ecosystems, as they provide food for fish and other marine organisms, filter organic matter from the water, and help maintain water quality. They are also used as indicators of water quality, as some species are more tolerant of polluted waters than others. Furthermore, some species are commercially important, due to their use in the production of ornamental items or as a source of calcium carbonate for the production of antacids and toothpaste.
