Lion cubs start hunting at young ages to grow the skills needed. Without preparation, then other animals would outhunt them, causing them to starve. However, the male lion cubs will eventually stop hunting and simply fight over females, leaving the female lionesses to hunt together.
In a lion pride, females are the hunters. The male defends his territory but leaves the hunting to the females because they are smaller and more agile. Each lion, whether male or female, has a specific role in the pride.
