Elephants are fond of the youngsters in the group and give them special care. They help young animals
stay afloat (漂浮着) when the herd crosses a river. They work together to rescue a calf (幼象) that has
wandered (迷路) into a dangerous place.
A female elephant that is about to give birth to (生产) her young leaves the herd for a short time. However,
she takes another female along to act as "aunt". The aunt stands guard and helps the mother with her new-born
calf. In this way, the whole herd protects its newest member.
