Differential interference contrast light micrograph of different species of fossil unicellular radiolarians (protozoa), from Barbados. Here, finely structured skeletons of different fossil types of radiolarian are seen. Made of silicates, the skeleton divides the inner cell nucleus and protoplasm from external protoplasm which extends out of the holes in the skeleton. In this way, radiolarians feed by trapping micro- organisms in the water. These tiny skeletons are among nature's most beautiful structures, and each species has a unique design. Plankton provides marine food.
