Most notably, protozoa within the subphylum Sarcomastigophora (the foraminifera, radiolaria, and acantharia; collectively referred to as "sarcodine protozoa") exist in symbioses with a wide array of algae (Anderson, 1983; Lee and McEnery, 1983; Caron and Swanberg, 1990; Michaels, 1991).

In most biological systems, preference in general is given to [Ca.sup.2+] over [Sr.sup.2+], although a marine organism, an Acantharia, constructs its internal skeleton of strontium sulfate [2].
