Why do some animals live in herds?

Living in herds provides animals with protection, access to resources, and social interaction. Herds reduce the risk of predation through safety in numbers, making it harder for predators to single out individuals. They also improve foraging efficiency by locating food sources more effectively. Additionally, herds facilitate communication and mating opportunities. Species like zebras, wildebeest, and elephants rely on group dynamics to enhance their survival in challenging environments.
