Blue Whales normally travel as individuals or in small groups of two or three animals, but in areas where krill are plentiful they can be found feeding in groups of 50 or more.
Blue Whales existed in large numbers until the early twentieth century. In a period of less than 40 years they were hunted nearly to extinction. As of 2002 there were 5 to 10 thousand worldwide and their numbers appear to be increasing.
