The blue whale name comes from the underwater colour, although his body is actually grayish-blue.
His diet mainly consists of krill, small crustaceans of which a blue whale can eat up to 4 tons every day (about two million of them!).
According to recent scientific studies, the life expectancy of a blue whale is up to 70-90 years and can be determined by the layers of their earwax.
