The New York World’s Fair. Please watch: "The New York World’s Fair, 1939-40"    • The New York World’s Fair, 1939-40   ~-~~-~~~-~~-~ The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). At up to 30 metres (98 ft) in length and with a maximum recorded weight of 173 tonnes (191 short tons), it is the largest extant animal and is the heaviest known to have existed. Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath. There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the pygmy blue whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill. https://en.wikipedia.org/wiki/Blue_whale By NOAA Photo Library - anim1754, Public Domain, https://commons.wikimedia.org/w/index... https://www.wikipedia.org/
