The big heart typically belongs to the blue whale, which is the largest animal on Earth. A blue whale's heart can weigh around 400 pounds (about 180 kilograms) and is roughly the size of a small car. This enormous heart is essential for pumping blood through the whale's massive body, supporting its size and extensive circulatory needs.
