What is a Marimo Moss Ball?

Despite the name, Marimo moss balls are not moss but a rare form of filamentous green algae (Aegagropila linnaei). These natural rolling algae spheres grow into perfect fluffy water balls in cold freshwater lakes where gentle currents shape them over time. Found in Scotland, Estonia, Iceland, Japan, and Australia, these aquatic plants have gained global recognition due to their unique formation, slow growth, and longevity.

They have even been featured in BBC’s Green Planet: Water Worlds, narrated by Sir David Attenborough, highlighting their ecological importance.
