Portrait of the loricate marine heterotrich ciliate, Metafolliculina producta. Most folliculinid ciliates are found in marine habitats. Metafolliculina producta is greenish-blue in color. This large species resides in a lorica that has distinct annular ridges toward the fluted open end. The highly contractile cell withdraws instantly into the lorica when disturbed (as seen in this image). The lorica is angulated but this feature is often not apparent due to compression by the coverslip. When fully protruded from the lorica the wing-like extensions of the peristomal area are evident. The cytostome lies at the central confluence of the peristomal wings. The somatic ciliation consists of uniform (holotrichous) longitudinal kineties. The genus Metafolliculina is distinguished from the similar Folliculina by its moniliform macronucleus (not well seen in this image). Collected from a commercial saltwater aquarium in Boise, Idaho February 2004. DIC optics.

The enthusiasm that many protistologists have for their organisms can be impressive. This crocheted representation of the ciliate was created by Maria Mulisch. I think the living populations of Euglena deses in ear-rings, migrating up and down through glass beads in response to long distant tidal and solar cycles was my favorite. There were of course the knitwares, the songs, even the website (damit).

Folliculina has mounted its lorica upside down on the Hyponeuston, the aquatic area closely attached to the water surface. Obviously the water´s surface tension was more attractive than the petri dish or bunches of filamentous algae. Sample from a little creek near Kiel. This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Folliculinid swarmer. Folliculinids are stunning spirotrich ciliates. The anterior part of the body is extended into two wings or arms, and the adoral zone of membranelles runs around the margins of these wings. They live in loricae which have a basal chamber and a longer neck. Folliculinids are contractile, extending out of the lorica when feeding and contracting into the lorica when stressed. Very often prettily coloured. When folliculinids divide, they produce a worm-like swarmer which does not have the developed arms. This is expressed from the lorica and swims or crawls around before finding somewhere to settle. Differential interference contrast.

Several nodes of the longitudinally oriented moniliform macronucleus are seen here along the margin of the cell (viewer's left).

When ciliates with lorica undergo a binary fission, one of them converts to a swarmer. The image shows a Eufolliculina swarmer which is looking for a suitable place to build his chitinous lorica. Collected from Bodden, the brackish waters lying between the isles of Hiddensee and Ruegen (German Baltic Sea). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Eufolliculina swarmer has found a suitable place to build his chitinous lorica. Now the cell is flattening and starts to segregate material to build up the bottom of the lorica and to connect it to the substratum. Collected from Bodden, the brackish waters lying between the isles of Hiddensee and Ruegen (German Baltic Sea). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Image of a Spirorbis shell - a marine polychaete. Folliculinids often occupy the depressed centre of the cell where they presumably are more sheltered from currents. The type of folliculinid is not known, but the tests with a basal ampulla, a narrower neck are typical of this group of ciliates. Many species have this dark green colour.

Lagotia, large folliculinid with an ampulla that lies on the ground and a cylindrical rising neck with spiral marks. With a compact macronucleus. Body variable in colour but usually blue green and with two broad arms. This image of a group of cells from Sagami Bay provided by Nishikawa Teruaki, of the Nagoya University Museum, Chikusa-ku, Nagoya 464-8601, JAPAN.

Ciliate from the family Folliculinidae, from a surface colonization experiment deployed at the margin of mangrove forest at Twin Cayes, Belize. The "bunny ears" are known as peristomal wings, and they carry part of the oral ciliature involved in feeding.
