Marsupials like the red kangaroo are born extremely underdeveloped (1g, 2cm, jellybean-sized) and must complete their development inside the mother's pouch for approximately 235 days, during which time they grow from barely formed hindlimbs to fully furred, hopping animals; female kangaroos can simultaneously carry joeys of different ages and produce two different types of milk tailored to each developmental stage.
