大自然很公平地对待动物王国中的每一个子民,两个敌手之间总有相互制约的因素,强者有“软肋”,弱者也有“杀手锏”,极少有百分之百的强者。在动物世界中,“刀兵相见”的天敌和猎物之间也存在着互为天敌的现象。 Nature treats each and every one of the people in the animal kingdom with fairness. There is always a factor of mutual restraint between the two adversaries. The strong have “weakness,” while the weak have “killers,” and rarely have a hundred percent of the strong. In the animal world, there are also natural enemy enemies and prey between each other.
