An armadillo is a small animal with a hard covering of bony plates on its back, like a suit of armour. It lives in parts of North and South America. Some kinds can roll into a tight ball when they are afraid; some cannot, and they run or dig instead. They have strong claws and often live in holes they make in the ground. You will meet them in zoos and nature films; they do not live wild in Taiwan. The English name is Spanish and means, roughly, “the little one in armour.” It is a mammal, not a turtle — a turtle's shell is a different kind of thing — and it is not a pangolin, though people mix those two because both look plated. The “arm” you can see in the spelling is the Spanish for armed / armoured, not the English word for the part of your body.
