Mammals are the only species to nurse their babies with milk produced by mammary glands. Male and female mammals both have mammary glands, but they only develop enough to produce milk in females. The one exception to this rule is the Dayak fruit bat. The males have mammary glands that are fully developed, and they feed their young with milk produced by these glands.

All mammals have three bones in their inner ears that are arranged in a pattern that is unique to mammals. These three bones are called the incus, malleus and staples. These bones transmit sound vibrations to the inner ear.
