Until now scientists had identified and named  about 5,000 different marine microbes, but a recent survey suggests that there could be over 100 times that amount living in our oceans.  Using a DNA probe marine biologists  found  20,000 microbes living in a single liter of seawater.

"A swimmer taking just a swallow of seawater may be consuming an entire zoo of 1,000 different forms of bacteria. That is how it seems the mysterious microbial world operates."

 The inside of the average surfer’s body must be a veritable zoo.
