8. Comparing animals
The blue whale’s tongue is also enormous—fifty people could stand on it, and it weighs about
3 to 4 tons. The blue whales mouth can expand hold a 100 tons of water, and 100 people
could be stuffed inside it.

9. One of the most remarkable organs of the blue whale is its heart. Imagine a heart about the
size of a Mini Cooper car and weighing 1,300 pounds! You could actually crawl through the
aorta, as this fiberglass model shows:
This enormous muscle pumps 14,000 pounds of blood through the whale’s body, and yet
this great heart beats only about 10 times a minute. Imagine the volume of each pump of
blood!
