Tokaanu geyser surrounded by bacteria

Tokaanu geyser surrounded by bacteria

This geyser at Tokaanu shows how the growth of thermophilic organisms is dependent on temperature. The bright orange and green patches are cyanobacteria living in the splash zone and outflow of the geyser. The orange cyanobacteria grow best in a ring around the geyser, while the green cyanobacteria grow in the much cooler outflow.
