'Blue Whales: Giants of the Ocean with Massive Organs'#fact #enigmarevealed

Blue whales are not only the largest animals on Earth, but they also have some of the largest organs in the animal kingdom. For example, their heart can weigh as much as a small car and is large enough for a human to swim through its major arteries. Additionally, their tongue alone can weigh as much as an elephant, making it one of the heaviest organs in any animal. These incredible sizes are necessary to support the massive body of a blue whale and its high energy demands for filter-feeding on krill.
