The blue whale is a giant of the oceans. It’s the length of a first-generation Boeing 737, a heart the size of a small car and a tongue the weight of an elephant. Because of its size, the giant is also a real eating machine. For example, he can eat 16 tons of krill per day in the eastern North Pacific, like a recent study in the journal Nature has now calculated. That is an estimated more than 120 million of the two centimeter large crabs.
