Detailed explanation-1: -Bats and whales are members of Class Mammalia. Bats are mammals which have wings and can fly, while whales are the largest animals in existence. Both bats and whales have four chambered hearts, but this is not the reason for them to be classified as mammals. They are mammals because of the presence of mammary glands.
Detailed explanation-2: -Millions of years before humans invented sonar, bats and toothed whales had mastered the biological version of the same trick – echolocation. By timing the echoes of their calls, one group effortlessly flies through the darkest of skies and the other swims through the murkiest of waters.
Detailed explanation-3: -An animal is considered a mammal if it can produce milk. Other features unique to mammals include hair or fur (chemically different from hairlike structures on non-mammals); the malleus, incus, and stapes in the ear; and a diaphragm separating the heart and lungs from the abdomen.
