Detailed explanation-1: -Zebras, bats, and bears do it. So do whales, tigers, and humans. These animals all nourish their newborn offspring with milk. It’s a defining characteristic of what it means to be a mammal.

Detailed explanation-2: -Well, even though some baby mammals are born different ways, they all drink milk that comes from their mothers’ bodies. Baby pigs, dolphins, bats and elephants all drink milk! Because the babies rely on their mother’s milk to live, the mammal mommies have to care for their young.

Detailed explanation-3: -All mammals are capable of producing milk, from the egg-laying monotremes like platypuses, to pouch-sporting marsupials like kangaroos and wallabies, and the more reproductively familiar rabbits, tigers, hippos, monkeys, and dolphins.

Detailed explanation-4: -Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all sexually mature female mammals, although it may predate mammals.
