A pangolin walks around, looking like a dinosaur

Pangolins are unique in that they are the world’s only scaly mammals. Their scales are made of keratin, which is the same protein found in rhino horn and human fingernails.Show more

These super-strong scales overlap like artichoke leaves, and when attacked pangolins roll up in a ball to protect themselves. However, this doesn't help them defend against poachers, who can just pick them up, put them in a sack and carry them off.

Pangolins have long, powerful claws that are perfect for ripping open ant nests and super long sticky tongues to pick up ants and termites. Their tongues are attached near to their pelvis and are sheathed in a chest cavity.
