How many species of fish does the earth contain ?

    Because scientists have yet to discover all the species of fish in the world, they can only estimate how many there are.  From a variety of sources, I’ve been seeing numbers between 20,000 to 40,000 different species.

    I would look at fish taxonomy/families before looking at specific species. A simple change in a gene sequence can evolve one species of fish, into another species of fish.

    To expand on previous answers, according to this article scientists are also discovering new species of fish at a rate of about two new species per week.
