We knew platypuses were incredible. Now we know they glow, too

The fur of the platypus glows under a blacklight—a finding that raises questions about its role in these strange mammals.

Just when I think they cant be any more absurd, the little fuckers surprise me again. Here’s some more interesting facts about the platypus:

  • They lay eggs.
  • Their closest living relative is the echidna, which also lays eggs. Platypuses and echidnas are the only two living mammals that lay eggs.
  • The male has venomous barbs on its hind legs. They are one of the very few venomous mammals. It’s non-lethal, but is one of the most painful stings of any animal. Morphine has no effect on the pain.
  • The female has two ovaries, but only the left one is functional.
  • They locate their prey in part by detecting tiny electrical signals caused by muscle contractions in the prey’s body.
  • Despite possessing mammary glands, they don’t have teats. Instead, they “sweat” it out of the pores in their skin and their young lap it off of their fur.
  • They have no stomach.
  • They have ten sex chromosomes. A male platypus is always XYXYXYXYXY.
  • Their young are born with teeth, but they fall out before they reach adulthood. Adults instead use gravel as makeshift teeth.
  • They have cheek pouches to carry their food in.
  • They walk on their knuckles.
  • They get the most REM sleep of any animal (5.8-8 hours a day).
