Introduction
The marimo moss ball, scientifically known as Aegagropila linnaei, was first described by Carl Linnaeus in 1753. Often found in literature under the outdated name Cladophora aegagropila, this unusual colony of green algae has been a beloved aquarium inhabitant for generations thanks to its undemanding nature and distinctive appearance. When cut open, it can be transformed into a living green carpet for creating picturesque underwater lawns.
