A Weak Biome

[Don Schaeffer]

This is rather an old biome in my collection. There is something of a biofilm coating on the water. There are some fast-moving protists which shot through the water so fast I couldn't photograph them. The bulk of is here are mature patches of passive biotic structures. The biome floats on the water almost like a coating.
