Science Friday (2/3): Platypuses hatch from eggs. As such, despite being mammals, they do not nurse their young.
Platypuses (Yes, that's actually the right word. While not incorrect, the terms "platypi" and "platypods" are used, but rarely.) do hatch from small, leathery eggs, but they're still mammals, and all mammals nurse their young.
But here's the funny part: platypuses don't have nipples. The mother platypus produces milk from her mammary glands, then oozes it out of ducts on her abdomen. The baby platypus then sucks the milk out of the mother's fur.
omg. those babies are so ugly they're cute
