Did you know that today is World Pangolin Day? It’s a whole day dedicated to celebrating and raising awareness about this unique mammal—which is not only the world’s only truly scaly mammal but also, unfortunately, its most trafficked. In honor of World Pangolin Day, here are five facts that you probably didn’t know about this interesting creature.

1. They wear heavy armor

The pangolin’s scales make up 20 percent of its total body weight.

2. They are toothless

Pangolins have no teeth; instead they rely on a gizzard-like stomach that is adapted for grinding food.

3. Their scales are dangerous weapons

Pangolins use their scales as tools for self-defense. If threatened, the pangolin will perform a cutting motion with its scales if anything is inserted between them—that’s a nasty shock for a strange paw or snout!

4. Their tongues may be longer than their bodies

A pangolin’s tongue can be up to 16 inches in length. They use these extraordinarily long tongues to reach insects burrowed underground.

5. They are threatened with extinction

Less than one year ago, the International Union for Conservation of Nature (IUCN) recognized the threat to Africa’s pangolins by scaling their status up to ‘Vulnerable’ due to the effects of illicit hunting and poaching.
