I have reported before on the ongoing Census of Marine Life which has turned up many strange and wonderful denizens of our oceans
One thing that is surprising, even if it should not be so, is the amount of microbial life in the seas.
According to an item on Phenomenica the census estimated there are somewhere in the order of a "nonillion" — or 1,000,000,000,000,000,000,000,000,000,000 — individual microbial cells in the oceans, weighing as much as 240 billion African elephants.
Wow! I suppose that is a hell of a lot of tuskers.....
