Whose is the world's largest brain?

Question

Whose is the world's largest brain?

Answer 1

The largest brain overall is indeed the sperm whale.

However, humans only have the largest brain to body size ratio amongst mammals.

Most birds actually have a much, much higher ratio of brain size to body ratio.  In humans, the brain is about 1/40 of the total mass, whereas in most birds it's actually about 1/12 of the total mass.  And that includes dumb birds like chickens.

The highest brain size to body ratio is actually in the small corvids - the blue jay, grey jay (also known as the Canada jay or whiskeyjack), and the magpies, and in some of the small passerines like chickadees and warblers.  Some of these critters can be nearly 10% pure brain.

Most of this is due to the adaptations that birds have to reduce their overall body weight in relation to flight, and highlights the importance of looking at more than just one statistic to quantify relative intelligence.

Answer 2

The largest brain is that of the Sperm Whale.

The largest brain in proportion to it's body size is the Human brain.

Answer 3

The largest brain on earth which is found in Sperm whales weighs on average the same as a 9 month old baby. That is ten times the weight of our brain! Wow!

Answer 7

Well! If you are asking about the weight it is sperm whale. but if you are asking about area, this credit goes to humans. Although we don't have very big brain in size still due to thousand of folds in brain make the area larger. The intelligence depends upon the area of brain not the weight. average human brain weighs around a pound (450 grams) & area around a football ground!!!! Bigger area, intelligent animal.
