A male lion is simply called a lion. Female lions are referred to as lionesses, and young lions are cubs. A group of lions is called a pride.
A pride of lions typically includes five or six lionesses, one or two male lions and the lions' young offspring. Litters contain between one and six cubs, and most of the lionesses in a pride tend to give birth at the same time. Lionesses usually remain in a pride for life, while male lions must fight to earn a place in a pride and then continually ward off challengers trying to take their place. Single males that live alone are called nomads. Occasionally, a female becomes a nomad.
