Lophophor
Lophophores are tentacle-covered wreath or arm-like organs that are primarily part of the nutritional apparatus. They are also known as a tentacle wreath . Lophophores are characteristic of the groups of organisms Brachiopoda , Bryozoa , Entoprocta and Phoronida . Lophophores are only found in aquatic creatures. The Lophophor is ring-shaped, horseshoe-shaped or spiral. The synchronized beat pattern of the tentacles creates a flow of water that carries food particles to the mouth. The anus is always located outside the ring when the lophophore is in a ring.
Animals with lophophores are summarized as Lophophoraten, in German wreath probe (also: Tentaculata), a meanwhile outdated classification as an animal strain. According to the current system, their representatives are counted among the Lophotrochozoa .
etymology
Lophophor is derived from gr. Lophos (tuft, crest , tuft) and -phor , -phoros (φορος) (carrier), a derivation of phérein (φέρειν) (to wear); the meaning is therefore: tuft carrier .
