An elephant has a long nose, because its long tube covered with elephant skin is like a horn. When the mother elephant wants to do year-end cleaning at home, the trunk is the best vacuum cleaner; When father elephant wants to water the flowers in his garden, the elephant's nose is the best watering pipe. Elephants have two big ears, which can usually hear any movement on the grassland and can also be used to drive away flies.
Elephants are the largest terrestrial social mammals in the world, and usually migrate in families. Elephant's cortex is very thick, but the skin between the folds is very thin, so mud bath is often used to prevent mosquito bites. Ivory is an important weapon to defend the enemy.
The ancestors of elephants appeared on the earth tens of millions of years ago. Elephant family used to be one of the most dominant animal groups on the earth, and more than 400 kinds of fossils have been found so far. However, due to historical climate and man-made reasons, there are fewer and fewer types of this ethnic group. At present, there are only 2 genera and 3 species of elephants on the earth: Asian elephant, African grassland elephant and African forest elephant, which are also seriously threatened.
