How intelligent is a sperm whale?
Like dolphins, whales are excellent communicators, and they show high levels of emotional and social intelligence. They also have very large brains, actually some of the largest. Sperm whales’ brains are the largest on the planet, with its weight being almost 5 times as much as a human’s.
Do Sperm whales have the biggest brain?
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don’t necessarily make a smarter mammal. The nocturnal tarsier is only 3.5 inches tall, but it has the largest eyes relative to body size of any mammal.
Are sperm whales smarter than humans?
Whales have pretty big brains. In fact, the largest brain on the planet belongs to the sperm whale. The sperm whale brain weighs about five times as much as a human brain. But just because you have a big brain doesn’t necessarily make you smarter.
How much brains does a sperm whale have?
Sperm whales (Physeter macrocephalus) have the largest known brain mass of any extant animal, averaging 7.8 kg in mature males. Bottlenose dolphins (Tursiops truncatus) have an absolute brain mass of 1,500–1,700 grams.
Is a dolphin smarter than a human?
While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts. Using brain size as a barometer, dolphins come in second only to humans in brain-to-body size ratio. However, dolphins also excel intelligence-based tests.
What is the most intelligent animal in the world?
Smartest Animals: Chimpanzees Chimpanzees are our closest living relatives, so its no surprise they make the list for most intelligent animals. We share almost 99 percent of our DNA (the little bits of genetic code that make us who we are) with them. It turns out that they share some of our brain power as well.
Which whale is the most intelligent?

How much do sperm whales brain weigh?
In fact the sperm whales brain weighs 5 times that of a humans brain! Although brain size has previously been used to correlate intelligence among various animal species recent research has shown that brain size does not always equal high intelligence, so the sperm whales brain size cannot be used as the only determining factor of intelligence.
What is the size of a whale brain?
Brain size tends to vary according to body size. The brain of the sperm whale is the largest, five times heavier than a human’s. The adult sperm whale brain is 8,000 cubic centimeters weighing about 8 kg (18 lb), while ours is about 1300 cubic centimeters.
