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. They are hermaphrodites, they change sex during their life span.Existing bryozoan colonial growth form classifications do not, however, fully exploit the ecological information present in colony form. A new scheme is proposed here (Analytical Bryozoan Growth Habit Classification), which provides a list of colony-level morphological characteristics for bryozoan growth habits.
