Many bryozoans are polymorphic with zooids specialized for different functions. Gymnolaemata C Gymnolaemate bryozoans are almost entirely marine and have circular lophophores. No epistome and no body wall musculature are present. These are considered to be derived characteristics. Colonies are polymorphic with specialization of zooids. Lophotrochozoa. Phylum: Bryozoa. The Bryozoans are commonly known as moss animals. They are also known as Ectoprocta and Polyzoa. They are a phylum of aquatic invertebrate animals. In size, they are about 0.020 inches long.
