""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)."

Triloculina (try-lock-you-lean-a) is an intertidal benthic foraminifer, with a small number of elongate chambers. Test usually said to be calcareous (porcellanous) but is brown coloured. With several major chambers. Pseudopodia mostly arise from the aperture (left). Dark ground

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.

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 species is often found in nearshore and lagoon environments; this one was collected at Laguna Madre, Texas. Image courtesy of Pamela Stephens, Midwestern State University.

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.
