Detailed explanation-1: -Although porcupines cannot shoot their quills, they can aim their body movements for vital places on the predator’s body. If the predator is hit, the quills can embed themselves in the animal because the body heat of the predators body causes the barbs to expand.
Detailed explanation-2: -Porcupines have soft hair, but on their back, sides, and tail it is usually mixed with sharp quills. These quills typically lie flat until a porcupine is threatened, then leap to attention as a persuasive deterrent. Porcupines cannot shoot them at predators as once thought, but the quills do detach easily when touched.
Detailed explanation-3: -Functionally, most spines serve as defense from predators, but spines are also important tools for communication, shock absorption, and rain protection.
Detailed explanation-4: -Porcupines are large rodents with coats of sharp spines, or quills, that protect them against predation.
