The largest whale recorded in history is the blue whale. Blue whales weigh up to 200 tons and grow to lengths of 100 feet. Their hearts weigh as much as an automobile, and their tongues weigh as much as an elephant.
The heaviest blue whale ever recorded weighed 418,877 pounds. It was captured in Southern Ocean, Antarctica, on March 20, 1947. The longest blue whale ever recorded measured 110 feet and 28 inches. It was captured in the South Atlantic in 1909. Blue whales are one of the Earth’s longest living animals. Their average lifespan is estimated at 80 to 90 years.
