All environments in this Zoo, including Water World, could be called Water World. However, some microbes prefer environments that have more water than the millimeters of water surrounding a particle of soil, or than is found in many foods. For this reason these organisms are grouped into habitats collectively known as Water World. There are many types of watery environments. These range from freshwater ponds to salty seas with three times the salt concentration of the ocean.
Microbes thrive in aerated streams with lots of oxygen to murky bogs that have no oxygen.
In this Water World are microbes containing tiny magnets and microbes that shine brilliantly in the night. In this pond, you will see many bizarre microbes including green and purple bacteria and algae, sulfate reducers, methane producers, and others. Check out Deep Sea Vents where life is truly bizarre. Life thrives at the bottoms of oceans near these vents. These are examples of microbes that have grown to become a biofilm.
