Radiozoa is a superclass of Rhizaria, a diverse group of eukaryotic microorganisms. These organisms are characterized by their intricate, often spherical, skeletons made of silica, known as tests.

These microscopic creatures are primarily marine, found in all oceans, from shallow waters to the deep sea.
Radiozoa move using pseudopods, which are temporary extensions of the cell membrane. These pseudopods extend through
