A group of spotted hyenas (called a "clan") can include 5–90 members and is led by a single alpha female called the matriarch. A complicated social hierarchy governs the clan, which cubs often learn before they begin to walk. Females are the dominant members, followed in rank by cubs, while adult males rank lowest. Male hyenas, which are usually smaller and less aggressive than females, often leave the clan when they are about two years old. Females tend to mate with males from other clans, thereby preventing inbreeding. Unlike many other animals, female hyenas very rarely mate with highly aggressive males. Instead, they select calm, patient and charming mates. Patience is especially important since courtship can last as long as a year. For this reason, dominant and impatient males have difficulty finding mates. Despite the complicated courtship, the female raises her pups without the male. Infanticide is comon "Prior to the mother's return, another adult female (a full sister to the new mother) arrived and methodically killed both newborns with crushing bites to the head" (Paula A. White)

On hunting: The spotted hyenas are an example of how the cooperative form of hunting can be dictated by the type of prey, as well as the predator’s ability to hunt and kill the different types of prey. When hyenas hunt an animal that is bigger than themselves, they act in a dog or wolf-like behaviour; hunting packs and together taking down the prey by biting and dragging it to the ground. If they are after smaller prey, they will hunt alone in a fox-like matter.

Like dogs, but unlike other animals in the same habitat, hyenas do not kill their prey directly. Having chased their prey to exhaustion, their prey is unable to mount any further defence of itself, and is captured and eaten while still alive. Although somewhat distasteful from the human perspective, the speedy disembowelment of the prey means that death often comes sooner than with the methods employed by other predators (for example, suffocation) and is an efficient means of eating which lessens the probability of the kill being lost to another predator.

Hyenas adapt their specific hunting strategy to the environment in which they live. In the Ngorogoro Crater, there is a very rich and concentrated amount of prey, and there are relatively many great beasts such as wildebeest or zebras. These animals are very much bound to one place and don’t migrate. Here, hyenas live in large clans (between 10 and 100 members per clan) and have established hunting territory which they often defend against neighbouring clans. The amount of large prey animals makes cooperative hunting more necessary than in the Serengeti, for example, where the clans often aren’t that large and must follow the herds when they migrate. Hyenas following migrating prey are less territorial, and will often hunt small animals individually as well as large ones in packs. An adult hyena is capable of taking down a fully grown wildebeest alone, but hunting in packs is proven to be more effective and fast . . .
