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. Here, they can be found in such habitats as marshes and abyssal plains where they move about and feed using their pseudopodia.

Some stone types, such as limestone, are commonly found to contain fossilized Foraminifera. Foraminifera are abundant in most marine environments so only small sediment samples (a few grams) are needed to obtain statistically significant numbers of microfossils to perform environmental analysis. This foraminifera has many shorter vertical partitions such as Colaniella. But, it is very small and the shape does not resemble Colaniella. Does someone know what is its genus? Foraminifera are known from early Cambrian times through to recent times.

The test of foraminifera can be very useful to modern day scientists. Most species of foraminifera are sensitive to changes in their environment in terms of salinity and temperature. This sensitivity allows preserved tests to be very useful indicators for environmental change on both a local and Foraminifera: Fusulina sp.
