Foraminifera
The chemical differences between Radiolarian and Foraminifera are in the types of shell casts they have developed. Radiolarians have siliceous shells, whereas Foraminifera have calcareous shells.
Foraminifera belongs to the kingdom Protista. They are single-celled organisms that typically have a calcium carbonate shell and are abundant in marine environments.
The foraminifers are unicellular organisms of the animal kingdom. Foraminifers are any of several large marine protozoans, of the subphylum Foraminifera, that have a calcareous shell with many holes through which pseudopodia protrude.
Globigerina is a type planktonic Foraminifera (a single celled organism with a small shell) that are found in the world's oceans.
The Foraminifera, are a class of amoeboid protists. They have thin pseudopodia that form an external net for catching food. They also usually have an external shell, or test, made of various materials and constructed in diverse forms.
When they die they leave behind their calcium carbonate shell.
What they are made of. Calcareous ooze is made from calium carbnate shells of cooclithophores, foraminifera, and other things with carbonate shells. Siliceous ooze is made of silica shells of radiolaria (really cool looking), diatoms, and anything else with a silica shell.
