Marimo Moss Ball Habitats


While looking for habitat-related activities, I ran across Marimo Moss Balls. These spherical algae balls grow in slightly brackish (salty) lakes in Japan. They were first made popular in Japan as “pets.” They require very little care; you just need to change the water every other week. I ordered them online and re-hydrated them when they arrived. The activity involved decorating mason jars with colored shell pieces, glass pebbles, tumbled glass, ribbons, or lace. Most decorations were hot glued on the outside of the jars, but some people made interior decorations. Here is a link to a Marimo care guide. Marimo can live up to 200 years if cared for correctly! Our teens were very excited about their new pets.
