Fish are the oldest vertebrates. Real fish first appeared more than 300 million years ago. Fish living on the earth today inhabit almost all aquatic environments on the earth, from freshwater rivers and lakes, clear mountain springs, icy polar oceans, to tropical coral reefs and pitch-black deep seas. These are their paradises. There are about 26,000 known species of fish in the world, accounting for about half of all vertebrate species.
