A herd is a group of animals of the same species that live and move together. Herds are commonly seen in species like cattle, sheep, and elephants. Living in herds provides safety in numbers, as it helps protect individuals from predators and increases the chances of finding food and water. Herd behavior is often characterized by social interactions and communication among members. Animals in a herd may follow a leader, and they often exhibit coordinated movements. This social structure can enhance survival and reproductive success, as members can share resources and support each other in raising young.
