PORCUPINE
DESCRIPTION
Also called the North American Porcupine, this species is a large rodent known for its coat of sharp quills that serve as a defense mechanism against predators. Porcupines are primarily nocturnal and are often seen climbing trees, where they feed on leaves, bark, and fruits. They have a stocky body, short legs, and a distinctive quilled tail, which they can raise to deter threats.
FUN FACTS
- Porcupines are known for their unique defense mechanism: when threatened, they can raise their quills and even charge backward into predators, embedding quills into their attackers
- Additionally, porcupines have a special relationship with certain trees, as they help in the growth of trees by feeding on their bark, which can stimulate new growth.| Porcupines are excellent climbers and often spend time in trees, where they can find food and avoid ground predators
- Their quills are not poisonous, but they can cause significant injury if they penetrate the skin of an attacker
