Blue whales are magnificent creatures. Their tongues alone weigh more than the average elephant, and their hearts can weigh more than a mid-size car. When the whales are fully grown, they can weigh up to 170 tons and measure nearly 100 feet long. The fin of the whale is so strong that it can capsize a good-size boat in one swoop.
The strongest land animal in the world is the African elephant. This strong mammal has the ability to lift over 600 pounds with its trunk alone. This animal can grow to be 11 feet tall and weigh nearly 6 tons.Learn more about Zoology
