 The crested porcupine has sharp quills all over its body that make it feared by many carnivores. It is covered from head to back with hollow black and white quills that can be up to 35cm in length. These quills are controlled by muscles, when in danger, it will rattle the quills to make noise to frighten the enemy. If threatened further, it will back into the aggressor and shoots the quills as weapons. Although the crested porcupines have sharp quills all over the top of their body, the abdomen are soft as their weak spot.
