10 20 called trunks, w eir mouths. Elephants cannot see very well. Their eyes are on the state of their heads, so they have to move 全体 their whole body to look at things. The phants have very good hearing, but 耳 they do not all have big ears. The elephants in Africa have very big ears. They 耳 use their ears to help them cool down on hot days. Elephants in other countries do not have such big ears. 両方とも Elephants live in both Africa and Asia. They can live for about 70 years. たいていの That is a long time. Most of an elephant's life is spent eating. Elephants spend 75% of their day eating. They eat a lot of plants and trees. They do not eat other animals. Elephants also need to drink a lot of water. They drink more than 250 liters of water a day. That is like drinking more than 700 small bottles of water a day. Elephants do not like to be on their own. They travel around in groups, いつも usuall 全体 aily with about 10 other elephants. When new elephants are born, the whole group helps to look after the new baby elephants. Elephants are very lucky because other animals do not attack them. クニッ Sometimes baby elephants are attacked by lions and crocodiles. However, 26 there is a bigger problem for elephants than lions and crocodiles. The bigger ~の部分 problem is humans. Humans kill many elephants. Parts of the elephant are 価値 worth a lot of money, so people want to get these parts and sell them. KR さらに、 ゾウ People also kill 'elephants
