This species is often found in Explorers Cove, a relatively quiet and undisturbed area on the coast of the Ross Sea.

Notice the prominent ridge along the outside of the coil, which gives this species its name. Image courtesy of Gudmundur Gudmundsson, Icelandic Institute and Museum of Natural History. This image was originally published in J. Foram. Res. 32:308-318, and is used with permission.

Notice the dramatic change in shape as the cell grows. The young foram produces a tightly coiled test (the whorl at lower right), but later growth spreads out n a disc-like shape.

This young foram is just bginning the change in growth pattern that is much more distinctive in the adult. Image courtesy of Gudmundur Gudmundsson, Icelandic Institute and Museum of Natural History. This image was originally published in J. Foram. Res. 32:308-318, and is used with permission.

This species is found in several places in the North Atlantic and the Arctic Sea. Image courtesy of Gudmundur Gudmundsson, Icelandic Institute and Museum of Natural History. This image was originally published in J. Foram. Res. 32:308-318, and is used with permission.

Notice the interior architecture of the test: a slightly ridged but undivided tube. Image courtesy of Gudmundur Gudmundsson, Icelandic Institute and Museum of Natural History. This image was originally published in J. Foram. Res. 32:308-318, and is used with permission.

This polarized-light image shows some of the "windows" that cover the surface of the test. Image courtesy of Samuel S. Bowser, Wadsworth Center.
-
The green color of this calcareous foraminiferan is due to the presence of symbionts. Notice the very large size of the test; this species can be well over 1 cm across. Image (and hand) courtesy of Samuel S. Bowser, Wadsworth Center.
-
This foram is extremely common in the Ross Sea (Antarctica). The "porcelaneous" structure typical of miliolid tests (rotalids have glassy "hyaline" tests) is very conspicuous here. Image courtesy of Samuel S. Bowser, Wadsworth Center.

An individual in natural surroundings. The test's chambers are particularly distinct in this photograph. The genus name
Sorites means "a heap" in Greek, and is also the name of a philosophical problem (the "
sorites paradox"). This paradox deals with the process of adding individual objects to a group: at what point do, say, individual sand grains added to a pile become "a heap of sand"? In this case, even though the foram adds its chambers one by one, it only takes one chamber to make a
Sorites. Problem solved. This individual was collected from Cook's Bay, Moorea, French Polynesia. Light micrograph by Scott Fay, 2005.

The biserial arrangement of the test (the youngest chamber is on top) is very evident here. Specimen collected from waters near Iceland.

Image of the holotype. This specimen is misidentified;
Flintina is not an agglutinated foram. However, identification is not possible without breaking open the holotype. Image courtesy of David B. Scott, Dalhousie University. This image was originally published in
