Why do lions roar?

Most members of the cat family are solitary hunters. They are adapted to living and hunting alone. Most of the wild cats would stay with their siblings until becoming sexually mature. At that point, they would separate from the group and continue on their own.

Lions are an exception to this rule. They are social animals, and they live in groups called pride with a strict hierarchy.

A major part of the pride consists of female lions, their cubs, and no more than two to three male lions. All members are loyal and dedicated to pride.

Pride is essentially a matriarchy. Females are responsible for hunting, guarding the territory, and taking care of the cubs.

Male lions are not contributing nearly as much. Their main roles are guarding the pride against other male lions and reproducing with the females. Other than that, they are famous for sleeping most of the day.
