Definition of Foraminifera:
(= foraminiferans) phylum of mainly marine unicellular protists (classified as protozoans of class Sarcodina in older zoological classifications), having a highly vacuolated outer layer of cytoplasm and a calcareous, siliceous or composite shell through which project fine pseudopodia. [1].
This is the common definition for Foraminifera, other definitions can be discussed in the article


Notes

Most foraminifera live on or within the seafloor sediment; they are a major components of many deep-sea oozes. Chalk is largely composed of foraminiferan shells. Most foraminifera are heterotrophic organisms (microzooplankton). See also wikipedia.
