How did blue whales get so big?

Pyenson and Vermeij hypothesize that marine gigantism was set on a fast track because of a particularly productive ocean during the onset of the Pleistocene, roughly 2.5 million years ago.

Giant ice sheets ground the earth into nutrient rich bits that found their way into the sea, potentially helping whales gain mass.
