Weirdness 9/10

The only mammal covered in scales that even lions can't crack

This is the only mammal on Earth covered head to toe in scales — and it rolls into a ball even lions can't crack.

The short version

The pangolin is the only mammal completely covered in keratin scales. It rolls into an armored ball that even lions give up on, has no teeth, and uses a sticky tongue longer than its whole body to eat thousands of ants and termites a day.

Why it's so weird

  • The Pangolin rolls into an armored ball so tough that even a lion usually gives up and walks away.
  • The Pangolin is the only mammal on Earth completely covered in scales.
  • The Pangolin is covered in hundreds of overlapping keratin plates, made of the same stuff as your fingernails.
  • The Pangolin has no teeth at all, yet slurps up thousands of ants and termites a day.
  • The Pangolin has a sticky tongue that can be longer than its entire body.

The full story

This is the only mammal on Earth that is completely covered in scales. Meet the pangolin, one of the strangest and most trafficked animals in the world. Its whole body is wrapped in hundreds of tough, overlapping plates made of keratin, the very same stuff as your fingernails. When a predator shows up, it tucks its head in and rolls into a tight armored ball, and those scales are so hard that even a lion usually gives up and walks away. But the weirdness is on the inside too. The pangolin has no teeth at all. Instead it has a sticky tongue that can be longer than its entire body, which it whips into ant and termite nests to slurp up thousands of insects a day. It even has special muscles to seal its nose and ears shut while it eats. Follow for more weird animal facts.
