Did You Know?

● The blue whale is the largest animal ever known to have lived on Earth.

● Calves nurse for seven to eight months, drinking 100 gallons of milk daily. 

● They can gain nine pounds in an hour and grow 1.5 inches each day.

● A blue whale's esophagus is only four inches in diameter — so swallowing large fishes isn't possible.
