Radiolarian protozoan. Coloured scanning electron micrograph (SEM) of the shell (test) of an unidentified radiolarian protozoan. This is a single-celled organism that forms part of the marine plankton. It builds this silicon-rich skeleton around itself for protection and support. It captures its prey,other single-celled organisms,by extending pseudopodia (false legs) of cell cytoplasm through the holes in its skeleton. Plankton forms the basis of most marine ecosystems.
