"Helping …"
Ifyour friend has a problem, you probably try to help him or her. However, do you know
animals also help each other?
In a film about animals, a zoologist explained that scientists were learning a lot about the s that animals behave. For example, he said that when he studied a group of dolphins, he saw ething unusual. Dolphins need air to survive, but one of the dolphins in the group was too weak vim to the top of the water. So, several dolphins quickly swam under him and pushed him to the ofthe water where he could get air. Then, they held him there until he was strong enough to alone. A scientist in Africa told another example of animals helping each other. The scientist was
hing a local elephant eating some leaves from a tree. Suddenly, another elephant arrived. als often attack other animals that enter their territory and eat their food, so what happened surprised the scientist. The second elephant was hurt and could not get its own food, so the first ant pulled a small tree from the ground and put it into the weak elephant's mouth. For that reason, there are some questions to answer. When animals help one another, does it nprove their chances of survival or are they just being nice? These are just some of the ons that scientists are still trying to answer.
