The elephant's legs are very thick and its feet are very big

The elephant's legs are very thick and its feet are very big. If you don't look carefully, you might think it has no toes. In fact, under the elephant's big feet, there are not only toes, but also oval nails. Their front feet have 5 toenails like human feet, and the hind feet have only 4, which is what we often call "front five and back four", which is also one of the signs of Asian elephants. Elephants also need to do "manicures" regularly. If the toenails are too long, they will bend or even grow inward, causing pain or infection. Elephants in the wild will "trim" their own nails. They usually use their feet to scratch the ground or find a rough stone to rub. They can do "manicures" for themselves without human intervention.
