I hope that you can learn from these photos that although fish have fundamentally similar structures, there are real differences that permit them to fill their niche and behave the way that they do.  Don't forget that these differences are a direct result of at least 400 million years of evolutionary processes that have resulted in over 24,600 living species (Moyle and Cech 1996, Fishes An Introduction to Ichthyology). 

 

You will find that the fish directly below have had the organs and structures labeled.
