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.

""Watermelon forams"--These foraminiferans possess chlorophyte (green algal) endosymbionts which give to the living cell a characteristic "grass green" coloration (specimen on right). Under high light (high UV?) conditions, the symbionts produce carotenoid pigments (salmon pink specimen on left)."

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.

Large disc-shaped soritid foraminifera. The test is calcareous, flattened and disc-like, cells may be several millimetres in diameter from Bahamas. This is an image of a dead test only, dark ground image by Dave Caron. This organism is found in benthic habitats.
