Pangolins
The pangolin has a body that is almost completely covered in large scales that kind of resemble a large pine cone. They live mostly in Africa and Asia, and they feed primarily on insects. While their outer body acts like armor, pangolins also use their large, powerful claws on their forelimbs as weapons.
The sharp edges of the scales protect the creatures from most predators, and any others that get too close will likely be hit by their powerful, heavy tail, which can cause serious injury. Another defense mechanism is the ability to curl into a ball and roll quickly down a slope at high speed. If that wasn’t enough, the last defense is the spray of a foul-smelling, gooey substance from the anus. Anything that wants to pick a fight with a pangolin may quickly regret that decision.
