It is triangular in profile with a heavily ciliated band called the corona at the base of the triangle and a sense organ at the apex ( cypho -, bent; nautes, sailor). The beating of coronal cilia propels the cyphonautes through the water and contributes to a feeding current.Bryozoans are microscopic aquatic invertebrates that live in colonies. The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch. Explain Bryozoa-Bryozoa is a phylum of aquatic invertebrates commonly known as moss animals or sea mats.
