A blue whale's brain weighs approximately 15 to 20 pounds (about 6.8 to 9 kilograms). This makes it one of the largest brains in the animal kingdom, reflecting the immense size of the blue whale itself, which is the largest animal on Earth. Despite its large brain size, the brain-to-body weight ratio is relatively small compared to other mammals.
The blue whale's brain is much larger and more complex than a human's brain. It is the largest brain of any animal on Earth, but its structure and functions are different from a human's brain.
