Interesting fact: The blue whale is the largest animal ever known to have lived on Earth, with some individuals weighing as much as 200 tons.
The answer: An adult blue whale can weigh between 100 and 200 metric tons (220,000 to 440,000 pounds), making it the heaviest animal on the planet.
Whales are marine mammals that vary greatly in size depending on the species. The blue whale, the largest of them all, can reach lengths of up to 30 meters (98 feet) and weigh as much as 200 metric tons. Other whale species, like the humpback or gray whale, weigh significantly less, typically ranging from 25 to 40 metric tons. These massive weights support their aquatic lifestyle and are essential for their survival in ocean environments.
