The largest animal in the world: Blue whale
The largest animal in the world is the blue whale. These ocean mammals can weigh up to 190,000kg, reach lengths of 30 metres (98 feet), and have a height of just under five meters (16 feet). The blue whale is so giant that its heart weighs as much as a small car and the arteries of its heart are so large that the average person could swim through them. A blue whale’s brain can weigh up to 6.8kg, making it the second-largest brain in the animal kingdom behind the sperm whale.
