What kind of behavior is also described as the selfish herd and benefits all members of all members of a population?

The behavior described as the "selfish herd" refers to individuals in a group positioning themselves to minimize their risk of predation by staying close to others. While it appears selfish, this behavior ultimately benefits all members of the population by enhancing overall safety through collective vigilance and dilution of risk. By clustering together, individuals can better protect themselves, leading to improved survival rates for the group as a whole.
