Marimo is a rare growth form of Aegagropila linnaei in which the algae grow into large green balls with a velvety appearance. The species can be found in a number of lakes and rivers in Japan and Northern Europe.
The remarkable shape and appearance of Marimo may not seem natural, but these moss balls are formed in nature with no interference from humans whatsoever. Marimo moss balls are a highly unique and rare form of algae growth. They can only be found growing in a few lakes throughout the world, which are located in Japan, Iceland, Scotland, and Estonia. As the algae grows in these lakes, the movement of the waves causes them to gradually form into spheres of soft, green algae with a fuzzy, velvet-like texture. Marimo balls are regarded as good luck charms in Japan, and since they have been known to live to 200 years or longer, they are often kept as family heirlooms. They are thought to symbolize close bonds between family members or close-knit friends, and are often passed down to children and grandchildren or nieces and nephews. By the time future generations receive the Marimo, they will be larger in size and will continue to grow with each generation. Additionally, Marimo are sometimes given to young children as "pets," since their care requirements are very minimal.
