Old lions still roar

At night, lions often let out a roar to let other animals know it is his territory.
Lions are very protective of their home, and a male lion, whose main job is to defend his pride, uses his loud roar to warn off anything that might threaten his family.
They also use roars to communicate with one another. Each lion makes a slightly different sound.
Lionesses use a very gentle roar when calling for their cubs, and even the big males use a softer roar when playing with their young.
