Acrosphaera radiolarian, SEM

Acrosphaera radiolarian. Coloured scanning electron micrograph (SEM) of the shell of a Acrosphaera sp. radiolarian. Radiolaria are single-celled protozoans that are found in marine plankton. This radiolarian has a silicate skeleton with pores through which pseudopodia (false feet) of protoplasm project. As it floats in ocean currents, the pseudopodia trap food particles on which the radiolarian feeds

EDITORS COMMENTS
This print showcases the intricate beauty of an Acrosphaera radiolarian, a single-celled protozoan found in marine plankton. The coloured scanning electron micrograph (SEM) reveals the delicate shell of this fascinating creature. With its silicate skeleton adorned with pores, the radiolarian possesses pseudopodia - false feet made of protoplasm - that extend through these openings. As it gracefully drifts along ocean currents, these pseudopodia serve as ingenious traps for capturing tiny food particles on which the radiolarian feeds. The circular shape and vibrant colors of this specimen make it truly mesmerizing to behold. Its presence in marine ecosystems contributes to the rich diversity of fauna and plays a vital role in sustaining life underwater. This image offers a glimpse into the hidden world of microscopic organisms that are often overlooked but hold immense importance within our planet's ecosystem. Through cutting-edge technology such as SEM, scientists can explore and study these unicellular creatures at an unprecedented level of detail. By unraveling their biological characteristics and behaviors, researchers gain valuable insights into various fields like biology and microbiology. This remarkable photograph is part of Science Photo Library's extensive collection, showcasing nature's wonders from a scientific perspective. It serves as a reminder that even within seemingly insignificant organisms lies extraordinary complexity waiting to be discovered by those who dare to delve deeper into the mysteries of our natural world.
