Monotremes, such as the platypus and echidna, are the most primitive mammals and lay eggs in a nest. After hatching, the young obtain their milk by licking milk patches on the mother's skin since they do not have nipples or mammary glands. Marsupials, apes, opossums, and kangaroos all give birth to live young and nurse them with nipples.
