Elephants have the biggest brain. It is difficult to measure the intelligence of a person or animal, but the coefficient of encephalization in an elephant is 1.88 (a man – 7.33, a chimpanzee – 2.45, and a pig – 0.27). Intellect and memory go hand in hand, suggesting that the elephant’s memory is good enough.

In addition, they can combine words and phrases in a variety of ways.
