Radiolaria are protozoa distinguished 1) by segregation of their soft anatomy into the central capsule, containing the endoplasm, and the surrounding ectoplasm (or calymma), and 2) by their siliceous (opaline) skeletons of the large majority of species.

Radiolaria can range anywhere from 30 microns to 2 mm in diameter. Their skeletons tend to have arm-like extensions that resemble spikes, which are used both to increase surface area for buoyancy and to capture prey.

Despite the large body of research surrounding these organisms, the classification of the Radiolaria has proven to be very difficult. The species that make up the Radiolaria have numerous unique characteristics, and yet this has has not helped to elucidate a definite scheme to classify these organisms.

Radiolaria are one of the most amazing groups of the protozoa. They are marine, pelagic organisms. They exhibit a complex endoskeleton, formed with silica, often radially symmetrical and very beautiful. The endoskeleton (a central capsule) covers a nucleated part of the cell and it separates this part from an ectoplasm.
