Genus Erethizon refers to a group of mammals that are commonly known as porcupines. Some of the synonyms for this species include Erethizon dorsatum, Coendu mexicanus, Hystrix dorsata, and Sphiggurus mexicanus. These animals are known for their distinctive spiky quills that protect them from predators. Porcupines have a slow pace but powerful claws that help them climb trees and move through dense forests to eat foliage, bark, and twigs. They are primarily nocturnal and solitary animals and their life span ranges from 5 to 7 years in the wild. Though generally peaceful creatures, their sharp quills can pose a serious threat to predators who dare to attack them.
