Of its 30 teeth, the four canine teeth are used to hold and puncture, while the four carnassial teeth cut through tough skin and meat. Lions live in prides , often consisting of four to twelve adult females, their cubs, and one to six adult males. The lionesses are usually related to each other and stay together for their lifetimes. They are the main hunters of the pride. The males leave the pride when they grow up and are replaced by newcomers, sometimes in deadly fights.
Lions are territorial .
The size of the territory is largely determined by the number of pride members and the amount of prey. It is the male's role to roar and mark its territory by urinating. The roar is often heard at dawn or dusk as a warning to intruders. Tracts of land, such as Kenya's Maasai Mara Game Reserve and the Serengeti National Park in Tanzania, have been set aside to protect lions and other wild animals. But as the human population grows, there will be more pressure to turn parkland into farmland.
