All mammals share certain characteristics, like warm blood and backbones. But despite their similarities, these creatures also have many biological differences — and one of the most remarkable differences is how they give birth. Kate Slabosky details the placental, marsupial, and monotreme methods of giving birth.

The three different ways mammals give birth - Kate Slabosky

All mammals share warm blood and backbones, but the ways they bring new life into the world are strikingly diverse. A newborn blue whale can already swim at 23 feet long, thanks to months sustained by its mother's placenta. Marsupials like kangaroos give birth to tiny, vulnerable babies who finish developing inside a pouch, while monotremes like the platypus defy expectations by laying eggs, yet still nurse their young. These varied strategies show how mammals adapt to thrive in many environments.
