Puma vs. North American porcupine (Erethizon dorsatum)…

Puma’s predation of the North American porcupine (Erethizon dorsatum)

Although also known as "porcupines", the spikes of members of the Erethizontidae family are far less lethal than those of the Hystricidae family. The latter has longer spikes and has a unique barbed structure on the surface. It is not only difficult to pull them out when they penetrate the predator’s body, but also as the movement of muscle tissue deepens, the former has no such spikes. The function of fear. As a result, Pumas are at much lower risk of hunting porcupines than leopards in the Old World, and although they may be coloured, they usually do not have serious consequences. There is no record of pumas being killed by North American porcupines.
