Here is a blurb from an article about a new species of whale. I attached the article if anyone is interested.
June 26, 2002 - In the mid-1970s, four rare beaked whales washed ashore dead on the coast near San Diego, California. James Mead, a leading authority on beaked whales from the Smithsonian, examined the skulls of these animals and tentatively identified them as the Southern Hemisphere species Mesoplodon hectori. At that time, there were a dozen named species of beaked whales (Ziphiidae) within the genus Mesoplodon that were diagnosed primarily by the size, shape, and position of an enlarged pair of teeth in the adult males. Two decades later, Merel Dalebout a graduate student from the University of Auckland analyzed DNA sequence data and found that these California animals clustered far apart on a phylogenetic tree from the Southern Hemisphere specimens of Mesoplodon hectori. Working together, Dalebout, Mead, and co-workers are now formally describing this heretofore unrecognized new species in the current issue of Marine Mammal Science (1). The new species, Mesoplodon perrini, is named after William F. Perrin, a preeminent marine mammal systematist and conservationist.
