Planktic forams grow their own shells using calcium carbonate, the material used to make the same shells you can find on the beach. Springer Science + Business Media New York, New York. Part 1 – areal distribution in the western North Atlantic. For example preservation of calcareous walled foraminifera is dependent on the depth of the water column and Carbonate Compensation Depth (the depth below which dissolution of calcium carbonate exceeds the rate of its deposition), if calcareous walled foraminifera are therefore not preserved agglutinated forms may be.

Foraminifera are abundant enough to be an important part of the marine food chain, and their predators include marine snails, sand dollars and small fish. Planktic foraminifera have been studied for their stable isotopic signals since the pioneering work of Urey [1947, 1948] and Emiliani [1954, 1955] and have since evolved into the primary carriers of paleoclimate data in marine environments.

In marine environments, Foraminifera are either planktonic or benthic. We emphasize studies of modern benthic and planktic foramin-iferal ecology that provide valuable insights into the original biocoenoses (life assemblages) of the upper reaches of the conti-nental … 89 effects on the core top planktic foraminifera sample material [Lea et al., 2000], the multispecies 90 equation of Sagawa et al. Today, an estimate of 4000 species live in the oceans. Tests of chitin (found in some simple genera, and Textularia in particular) are believed to be the most primitive type. Foraminifera are marine protozoa that are characterized by having tests (shells) that supports the cellular material.
