This is a bonsai.
Marimo is a kind of alga. It forms beautiful
green ball.
It lives in specific cool lake, example Akanko lake is famous in Japan.
It becomes round itself, otherwise wave or flow may make it round.
Natural marimo needs one or two hundred years to grow to two inches diameter,
and it becomes to a foot diameter maximum.
It should be protected.
My marimo was farmed for sale.
