Lophophore

:
The lophophore is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Entoprocta, and Phoronida, which collectively constituted the Lophophorata.〔(Introduction to the Lophotrochozoa ) - accessed 3 May 2010〕 All lophophores are found in aquatic organisms.
==Characteristics==
It can most easily be described as a ring of ciliated tentacles surrounding the mouth, but it is often horseshoe-shaped or coiled. Phoronids have their lophophores in plain view, but the valves of brachiopods must be opened wide to get a good view of their lophophore.
The lophophore surrounds the mouth and is an upstream collecting system for suspension feeding. Its tentacles are hollow with extensions of a coelomic space thought to be a mesocoel. The gut is U-shaped with the anterior mouth at the center of the lophophore. The anus, where present, is also anterior, but is dorsal to the mouth. In the Bryozoa it is outside the ring of the lophophore; in the Entoprocta the anus is within the ring of the lophophore. Some brachiopods do not have an anus.
