A female mammal is a member of the class Mammalia that possesses two key characteristics: mammary glands and the ability to give birth to live young (with some exceptions, like monotremes). Female mammals typically nurse their offspring with milk produced by these glands, which is essential for the young's growth and development. Female mammals can be found in various species, including humans, dogs, cats, and whales. They exhibit a wide range of behaviors and adaptations, depending on their environment and lifestyle. Female mammals often play crucial roles in their social structures, particularly in nurturing and protecting their young.
