Some Facts

In the past I have learned that more than 70% of the earth's surface is covered by salt water and only 1% by freshwater. by volume about 97% of water is contained in the oceans, while only approxamately 0.0093% is in freshwater lakes and streams and the remainder is in ice, atmospheric water, etc. From those numbers it would be expected that the majority of fish lived in a marine environment, but only about 58% are marine and 41% are freshwater, the other 1% moves regularly between the two environments.
