New genetic research has identified fin whales in the northern Pacific Ocean as a separate subspecies, reflecting a revolution in marine mammal taxonomy as scientists unravel the genetics of enormous animals otherwise too large to fit into laboratories.

“The increasing study of cetacean genetics is revealing new diversity among the world’s whales and dolphins that has not been previously recognized,” said Eric Archer, a geneticist at NOAA Fisheries’ Southwest Fisheries Science Center (SWFSC) in La Jolla, California. Archer is the lead author of the identification of the new subspecies of fin whale.
“There’s definitely more diversity out there than has been on the books,” he said. “There has been a wave of progress in cetacean taxonomy.”
Fin whales are the second-largest whale on earth and the fastest whales in the ocean, which made them one of the last whale species hunted to the edge of extinction. Whalers killed about 46,000 fin whales in the North Pacific Ocean from 1947 to 1987. They are also one of the least known large whale species. They mainly roam the open ocean, farther from coastlines where they might be seen and studied more easily.
