Ed Yong has written a great post on a new paper on how blue whales snarf up half a million calories in every gulp. The paper is the latest in a series put out by Jeremy Goldbogen of Scripps Institution of Oceanography and his colleagues. If you want to dig back into the earlier research, check out my 2007 New York Times article and this Loom post on how a physicist who studies parachutes helped solve the mystery of big gulps.
