All lions have tawny brown fur (apart from white lions) that has spots on when they are young. They have a lighter coloured tummy and muzzle. Lions have a brown tuft on the end of their tails. Male lions have a thick, downy mane that grows as they get older. A mane starts growing when a lion is an adolescent (teenager) and starts of the colour of the lions fur. A lion gets a type of under-arm hair which is part of their mane when they get older. A lions mane colour ranges from brown to black.
