Figure 8.

Lions mating in the Masai Mara of Kenya, with the male's grimace and female's reaction at the moment of ejaculation. The female mates with many males before “committing” her eggs to fertilization. When she accepts a male, they often copulate every 15 minutes for 3 days and nights, the male never letting her wander more than a few feet away. Infanticide by new males that take over a pride may help explain her delay in ovulating, as she may be testing the stability of her pride's male coalition.
