Which animal has the biggest brain in proportion to its body?
Answer:
The sperm whale is supposed to have the largest brain in the world, as far as mass and size of the brain alone, not in proportion to its body size.
Speaking in terms of mass and in proportion to body size, it is common knowledge by many that the human has the biggest brain in such proportions. A human's brain has a brain-to-body ratio of 1/40. This means that your whole body weighs 40 times more than you brain does. However, in terms of proportion to body size, the human is not the candidate for biggest brain.
Here are some known brain-to-body mass ratios of common animals in descending order:
Humming bird: 1/25
Squirrel monkeys: 1/32 to 1/20
Mice: 1/40
Humans: 1/49
Cats: 1/100
Dogs: 1/125
Frogs: 1/172
Lions: 1/500
Elephants: 1/560
Horses: 1/600
Sharks: 1/2500
Hippos: 1/2700
As you can see, humans do not have the largest brain-to-body mass ratio. Intelligence isn't directly linked to the size of a brain, but instead to the brain's structure.
