The animal with the largest brain in proportion to its body size is the sperm whale. The sperm whale has a brain that weighs around 17 pounds (7.8 kg) which is the largest brain of any animal that has ever lived on Earth. This massive brain makes up about 0.02% of the sperm whale's total body weight.

The brain of a sperm whale is the largest brain of any animal both in absolute mass and relative to body size. Sperm whales are able to dive to great depths and hunt for food using a process called echolocation. They use their large brain to help them navigate and communicate with other whales, making it an essential part of their survival in the deep ocean.
