Which animal has highest Encephalization quotient?
Animals with very large flock size and/or complex social systems consistently score high EQ, with dolphins and orcas having the highest EQ of all cetaceans, and humans with their extremely large societies and complex social life topping the list by a good margin.
Which hominid had the largest brain?
Homo neanderthalensis
The volume of the human brain has increased as humans have evolved (see Homininae), starting from about 600 cm3 in Homo habilis up to 1680 cm3 in Homo neanderthalensis, which was the hominid with the biggest brain size. The increase in brain size stopped with neanderthals.
Are whales more intelligent than humans?
Whales and dolphins are smart! The evidence is that – in some ways – whales and dolphins have communication abilities that are superior to those of human beings. Dolphin communication is so great that there is a strong possibility that a dolphin can send a sound image of say a fish to other dolphins.
How large is a whales 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. A human brain can weigh 1.5 kg in adulthood.
What mammal has the smallest brain?

How heavy is a whales brain?
A mature male sperm whale can have a brain that weighs up to 9kg, and killer whale brains can reach 6kg. In contrast, the average human brain is only 1.4kg.
How big is a whale’s brain?
Size matters, but it’s not everything The largest brain on earth belongs to the sperm whale, the same species as the main character in Melville’s yarn. The adult sperm whale brain is 8,000 cubic centimeters.
Do whales have more cortical convolutions than humans?
Cetacean brains, such as those of dolphins (left) and humpback whales (right), have even more cortical convolutions and surface area than human brains do.
How smart is a sperm whale’s brain?
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 largest whale in the world?
Reaching lengths of up to 67 ft. long, the sperm whale is the largest known whale within the toothed whale family. The sperm whale also happens to have the largest brain and cerebrum of any known mammal in existence today. In fact, the sperm whale’s brain weighs 5 times that of a human’s brain!
