Name them Saitama and Satoshi.

I googled the unfamiliar title and here's what I found:

The existence of Marimo colonies in Lake Akan, Hokkaidō in Japan and in Lake Mývatn in Iceland depends on the adaptation of the species to low light conditions, combined with the dynamic interaction of wind-induced currents, light regime, lake morphology, bottom substrate and sedimentation.

Since a significant portion of them live in Japan, my name nominations are also Japanese. Just a remainder, they are rare species and need to be protected:

The rapidly declining population of lake balls in Mývatn is of special concern, but for unknown reason some of the main patches have all but vanished in recent years.
