How blue whales became the largest animals to ever live on earth
In a study published this week in the Proceedings of the Royal Society B scientists have zeroed in on the cause and effect of blue whales colossal size. The scientists equated whale gigantism to climatic change and greater food source. Since baleen whales such as blues, fins, and bowhead whales filter feed on small organisms, a boom in krill and other similar food sources sparked the leap to giant size. Prior to the boom, which correlated with ice sheets covering the Northern Hemisphere 4.5 million years ago, blue whales were a fraction of the size they are today.
