This specimen was collected on Sapelo Island, Georgia. The nearly transparent tendrils extending from the test are the reticulopodia. The green color is caused by chloroplasts that the foram has stolen from diatoms that it eats. Image courtesy of Susan T. Goldstein, University of Georgia.

This image shows a closeup of the aperture in the test from which the reticulopodia extend. The actual aperture follows the curved line between the glassy-looking part of the test, which is the youngest chamber, and the yellowish part, which is another part of the test (and out of the plane of focus, which is why it's slightly blurry.) The pods themselves are the transparent ray-like objects. Forams use reticulopods to move, eat, gather materials, build their tests, and do pretty much everything else they do.

Electron micrograph of an individual recovered from the Santa Barbara Basin, California. This species is found at the most anoxic part of the basin; it can apparently survive for months with no oxygen. Length: about 300 um.

Sample collected at Hamble Estuary, Hampshire, England. Bolivinids are generally found in the estuary only in fall and early winter, when river water flow is low and salinity is relatively high.

This is the top (spiral) surface of a gamont of Ammonia parkinsoniana. Forams have complex and varied reproductive cycles. Some forms, such as this species, alternate between agamonts/schizonts (which are produced when two gametes fuse) and gamonts (which are produced when an agamont splits up into hundreds of smaller individuals). The two types often look so distinct from each other that they were originally mistaken for different species. Image courtesy of Pamela Stephens, Midwestern State University.
