阅读第一篇好像没有在寂静看到 是一个动物叫tabhole?讲鱼是他的捕食者,不长,分两段。第一段说因为捕食者,他会有啥表现,比如不怎么活动啊啥的,这里有题,问他活动的话可能是干嘛,我选的forging在文里有提的。也说他们会抱团,有两个cue,就好像抱团了自己被吃的几率就小点儿。第二段就是科学家发现观察一个类的那玩意,不活动啊那些都是印证了自己的预期,但是抱团没有,觉得可能他们研究的对象现在抱的团太小了,没有预期效果。
Zoologist: Meerkats are desert mammals that live in groups and are believed to exhibit altruistic behavior. While the group is foraging, a single meerkat will stand guard, keeping watch for predators and giving loud warning cries when danger appears. However, this behavior is not true altruism: Meerkats on guard duty do not face a greater risk of being killed, and solitary meerkats will also stand guard.
