Elephants are animals that everyone knows well. They have a unique appearance, huge ears, slender and long trunks, huge bodies, strong limbs, and heavy feet. But there are also things about elephants that people don't know about. Today we will introduce to you a little-known side of elephants.

In the animal kingdom, elephants are not great in many ways, but their memory is superb. Humans have studied the elephant for many years, and the more we learn about it, the more we admire its amazing memory. That's not to say the elephant is a giant removable disk that stores everything. Rather, it has infinite intelligence, and that intelligence makes it the friendliest, most social, and creative animal on the planet.

The elephant's brain is the largest of all land mammals, and its brain quotient should not be underestimated. Let’s talk about the brain quotient first. This quotient is the result of dividing the size of the biological brain by the size of the biological body. It can be used to express the intelligence of the brain. Its brain quotient is almost as high as that of a gorilla, and convergent evolution has allowed its brain to present a structure similar to that of the human brain.

Its brain has many neurons and synapses, as well as a highly developed hippocampus and cerebral cortex, which is closely related to emotion. This allows it to inscribe important experiences into long-term memory, and this partitioning function of importance makes an elephant's memory a complex and adaptive vehicle. This also allows their memory to far exceed mechanical memory.

Throughout their lives, elephants will not only remember the companions they spend with each other, but also other animals that have left a lasting impression on them. Two elephants once performed in the same circus. After the performance, they separated for more than 20 years, but when the two elephants saw each other again, they were as happy as seeing old friends. The memory of elephants is not limited to the same kind, but also the same with people or other types of animals. If you have a bond with an elephant, it will recognize you in the crowd even after many years, even though you may have long since forgotten it.

In addition to memory, the cerebral cortex also gives elephants the ability to deal with problems. They are super cooperative, and at the same time they have basic computing power. This rare combination of memory and problem-solving can explain some of the most intelligent behaviors of elephants.

As a very intelligent animal, the group of elephants also shows a very prosperous scene. Elephants are very compassionate, and they usually comfort each other and use their trunks to soothe their companions. When a member of their group dies, they even take the initiative to help their companions bury, and they will stand in a row collectively and hold a "funeral". When they see a companion in a quagmire or encounter other difficulties, they will also take the initiative to help rescue them. According to research, an elephant can distinguish the voices of more than 100 companions, which is difficult for humans to do.
