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). Phase contrast.

Hauerina ornatissima.
-
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.

Vertebralina insignis.
-
This specimen was collected off the South Texas coast, but is more commonly found in deeper water. Image courtesy of Pamela Stephens, Midwestern State University.
-
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.
