Oscillatoria blue-green alga
Light micrograph of Oscillatoria sp. (brown strands), a filamentous blue-green alga or cyanobacterium. The strands of alga are in fact linear colonies of primitive, single-celled, prokaryotic organisms, more closely related to bacteria than to algae. They are considered to be one of the most primitive organisms, dating back to pre-Cambrian times. The strands (known as trichomes) of Oscillatoria exhibit swaying motion & can also move backward & forward. The mechanism for this movement is not yet fully understood.

EDITORS COMMENTS
This print showcases the intricate beauty of Oscillatoria, a filamentous blue-green alga or cyanobacterium. The brown strands depicted in this light micrograph are actually linear colonies of primitive, single-celled organisms that belong to the prokaryotic group and are more closely related to bacteria than algae. With their origins dating back to pre-Cambrian times, these fascinating organisms represent some of the most ancient life forms on Earth. What makes Oscillatoria truly mesmerizing is its unique ability to exhibit swaying motion, akin to delicate dance moves. These slender trichomes can gracefully move both backward and forward, creating an enchanting spectacle for observers. Despite extensive research conducted on this phenomenon, scientists have yet to fully comprehend the mechanism behind this intriguing movement. The magnification used for capturing this image was x200 at 35mm size, allowing us to appreciate even the tiniest details of these remarkable organisms. This nature-inspired photograph not only highlights the botanical wonders found in our world but also emphasizes the significance of algae within ecosystems. Displayed by Science Photo Library, renowned for their exceptional scientific imagery collection, this print serves as a testament to nature's endless marvels and invites viewers into a realm where science meets artistry.
