Lophotrochozoa is a monophyletic group of animals that includes annelids, molluscs, bryozoans, brachiopods, platyhelminthes, and other animals that descended from the common ancestor of these organisms.Ontological in Law. In Right, the ontological refers to the legal ontology, which is a branch of the philosophy of law whose object of reflection is the nature or essence of the being of law.In this sense, it tries to unravel what makes something legal, for which it considers, on the one hand, the object and rationale of the Law and, on the other, it postulates the …Bryozoans: characteristics, morphology, reproduction, nutrition The bryozoan They are a group of animal that are alo known a ectoprozoa.

Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres (1 ⁄ 64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.

Lophophorate, any of three phyla of aquatic invertebrate animals that possess a lophophore, a fan of ciliated tentacles around the mouth. Movements of the cilia create currents of water that carry food particles toward the mouth.

An individual zooid consists of a partially protrusible organ system (= polypide) surrounded by a body wall. The polypide bears a large retractable lophophore with cilated tentacles used to collect food.
