Foraminiferan, any unicellular organism of the rhizopodan order Foraminiferida (formerly Foraminifera), characterized by long, fine pseudopodia that extend from a uninucleated or multinucleated cytoplasmic body encased within a test, or shell. Depending on the species, the test ranges in size from minute to more than 5 cm (2 inches) in…

2 dagar sedan · Foraminifera are very small sea organisms that create calcium carbonate (CaCO3) shells to protect themselves. When they make their shells, they incorporate oxygen from the ocean, which contains both 16 O and 18 O, and as a result, scientists can use foraminifera shells to obtain delta-O-18 values and to determine the ocean temperature at the time of the shell's creation.

Foraminifera, or forams for short, have amoeba-like bodies within tests that are generally made of calcium carbonate. They have one or more openings through which the foram can extend its body by means of thin, threadlike projections called pseudopods.

While the phylum has also been shown to consist of several slime moulds and Foraminifera, it's mostly composed of naked and testate amoebae. Unlike naked amoebae, testate species are covered by a shell-like structure which may consist of small grains of sand, diatoms, mineral particles, and silica plates.
