These unicellular creatures construct unusually complex networks that ar This foraminifera was collected as it floated about 3 meters below the surface off the coast of Puerto Rico. The central dark area is the shell surrounded by spines. The tiny yellow dots are symbiotic algae, which live in the protoplasm of the host organism.
The proloculus is the first chamber of the test. It is small when the foraminifera has formed by sexual reproduction, but large when reproduction has been asexual. Protoplasm is the soft, jelly-like material that forms the living cell of the foraminifera… Foraminifera Ecology In marine environments, Foraminifera are either planktonic or benthic. Typically, Benthic Foraminifera are bottom dwellers and thus reside at the seafloor.

Collection Patrimoines Naturels, 50: pp. 60-75 (look up in IMIS) Foraminifera can also be utilized in Archaeology in the provenancing of some stone raw material types. Some stone types, such as limestone, are commonly found to contain fossilized Foraminifera.
First identified in the 5th Century, the Foraminifera species are single-celled protozoans commonly found in marine environments (some are much bigger in size).

When they die, their hard shells are incorporated in the surrounding sediments and buried over time in a nearly uniform layer. Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood.
