Taxonomy of Fish

My post today is a brief presentation of the taxonomy of some of the significant fish found in the vicinity of the Mid-Atlantic of the eastern United States and in the adjoining waterways.

Amongst the vertebrates, fish are unique insofar as they compose three classes -- while birds, reptiles, and amphibians, are each a single class of the phylum.

Of course, any taxonomical list is subject to dispute, and fish are no exception.  Nevertheless, this seemed resonable to this blogger!
