Mammary Glands. Mammals nurse their young with milk produced by mammary glands. Mammary glands, like hair, are a uniquely mammalian trait. Though present in both males and females, in most mammal species mammary glands only fully develop in females.The exception to this rule is the male Dayak fruit bat, which has mammary glands that produce milk to feed its young.ot all mammals have nipples. Monotremes, which include echidnas and the platypus, diverged from other mammals early in their evolution. Monotremes lack nipples and instead secrete the milk produced by their mammary glands through ducts in their abdomen.
