Foamy Yellow Biome with Active and Passive Life Forms.

[Don Schaeffer]

I guess this kind of growth pattern can best be described as broad-based or multiple form. Most of the organisms are of that mysterious stationary sort but a minority are active protists. I don't know how these life forms collect in a biofilm or inside a water sample but the patterns and population types are regular.
