Radiolarian planktonic protozoan, SEM
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. Magnification unknown

Plankton Planktonic Protozoa Protozoan Radiolaria Radiolarian Test
EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of a radiolarian planktonic protozoan. The coloured scanning electron micrograph (SEM) reveals the shell, or test, of this unidentified single-celled organism that thrives in marine plankton. Radiolarian protozoans construct their silicon-rich skeletons as a means of protection and support within their watery habitat. Through these shells, they extend pseudopodia - false legs made up of cell cytoplasm - to capture prey consisting of other single-celled organisms. The magnification level used to capture this image remains unknown, but it allows us to appreciate the remarkable details and complexity present in even the tiniest creatures inhabiting our oceans. Plankton plays an essential role as the foundation for most marine ecosystems. These microscopic organisms form a crucial part of the food chain, sustaining larger aquatic life forms such as fish and whales. Science Photo Library offers us an opportunity to explore nature's wonders through its vast collection of images like this one. This particular photograph not only highlights the extraordinary world hidden beneath our seas but also serves as a reminder that there is still so much left undiscovered and awe-inspiring about our planet's wild life and natural phenomena.
