The three different ways mammals give birth

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. [Directed by Compote Collective, narrated by Julianna Zarzycki, music by Big Banda Soundscapers].
