On the organization of the lophophore in phoronids (Lophophorata: Phoronida)
Russian Journal of Marine Biology, 2009The organization of the lophophore is the main feature used for the identification of phoronid species. The structure of the lophophore and tentacles in seven phoronid species (Phoronis ovalis, P. ijimai, P. hippocrepia, P. svetlanae, P. australis, Phoronopsis harmeri, and Ph. malakhovi) collected in different areas of the World Ocean was studied.

Colonial Nervous Control of Lophophore Retraction in Cheilostome Bryozoa
Science, 1975Nervous impulses causing lophophore retraction over large areas of Membranipora membranacea and Electra pilosa were recorded with external electrodes. The response propagates at about 100 centimeters per second, presumably through the colonial nerve plexus of Hiller and Lutaud.

NOTES ON THE LOPHOPHORE AND GUT OF THE BRACHIOPOD
Proceedings of the Zoological Society of London, 1963The lophophore of the rhynehonellid brachiopod Notosaria nigricans from New Zealand develops through trocholophous and schizolophous stages before reaching the final spirolophous condition. This development, and the structure and elliation of the spirolophe, are described in detail.

Hemoglobin Function in the Lophophorate Phoronis architecta (Phoronida)
Physiological Zoology, 1991The function of hemoglobin-containing red blood cells in O₂ transport and storage was examined in a tube-dwelling marine animal, Phoronis architecta. The maximal rate at which O₂ could be transported by the circulation in one animal (≈ 0.014 g) was 0.0018 μp mol O₂ · h⁻¹ in physical solution and 0.054 μmol O₂ · h⁻¹ by hemoglobin (both computed at Po₂ =

Functional disposition of the lophophore in living Brachiopoda
Lethaia, 1992Emig, C. C. 1992 07 15: Functional disposition of the lophophore in living Brachiopoda. The shape and disposition of adult brachiopod lophophores relate to in- and excurrent apertures. to the internal water irrigation system, to shell orientation at substratum and to near-bottom currents.

Microarchitecture and function of the lophophore in the bryozoan Cryptosula pallasiana
Marine Biology, 1974The architecture and function of the lophophore of the marine bryozoan Cryptosula pallasiana (Moll) are described, including some new features not previously discovered in bryozoans. The nature of fluid movements within the lophophoral coelom during feeding activities is postulated on the basis of the arrangements of epithelia and muscles.

The method of feeding of lophophorates (bryozoa, phoronida, Brachiopoda)
New Zealand Journal of Marine and Freshwater Research, 1968Summary The lophophorates all feed by “impingement” feeding, so named by analogy with certain types of particle separators used in industry. In gymnolaemate bryozoans the feeding current is directed at the mouth where particles impinge and are sucked into the pharynx; in phylactolaemate bryozoans the particles ...

The Lophophorate Phyla Phoronida, Bryozoa, And Brachiopoda
1990Abstract The Phoronida, Bryozoa, and Brachiopoda are smallish phyla of quite different outward appearance; yet they are linked by a common body plan. In all three the body is coelomate and divided into three regions. The mouth is situated within the lophophore, which is a crescentic or annular ridge bearing slender ciliated tentacles and
