Pack hunterとは 意味・読み方・使い方

A pack hunter is a predator belonging to the animal kingdom, which has evolved to hunt its prey by working together with other members of its species. Normally, such animals are closely related. The most commonly-known pack hunter is the Gray Wolf, the ancestor of all breeds of domesticated dogs. This pack-hunting history is thought to be the main conduit through which humans have been able to form a mutual relationship with dogs (that is, domestication), as both species are highly social and inter-dependent. Humans and their closest-living relatives chimpanzees are themselves pack hunters even without aid of other species. Other pack hunters include simple arthropods such as ants, highly intelligent mammals such as dolphins, orcas, lions, and hyenas, a few birds such as the Harris Hawk, and occasionally crocodiles. There is a possibility that some non-avian theropod dinosaurs displayed pack behavior as well.
