A group of mostly female lions is called a pride, and a group of male lions is called a coalition. The pride contains female lions and their young offspring, and usually has fewer than 20 members. A coalition of male lions usually includes less than 10 individuals.
A coalition of male lions often fights with other coalitions to have access to the female pride. The association between a coalition and a pride usually lasts for a few years until time and danger result in a different coalition gaining access. Male lions compete to mate with the female lions, but it is the females who choose their partners.
