Prof reports 15 new fish species in US

They are not all confirmed yet, but I thought this university press release was interesting. One ichthyology professor, Austin Peay State University's Dr. Rebecca Johansen, is reporting that she and her students have gathered evidence of up to 15 new species from the southeastern U.S. Wouldn't you think that was an area where all the vertebrates are known? It's a good reminder that we rarely know the natural world as completely as we think we do.
