Definition & Meaning of "porcupine"

What is a "porcupine"?

Porcupines are slow-moving mammals known for their distinctive appearance, characterized by their spiky quills or spines that cover their bodies. They are typically nocturnal and solitary animals found in various habitats, including forests, deserts, and grasslands in different parts of the world. Porcupines have a stocky body with short legs and a small head, and their quills are modified hairs that provide them with defense against predators. When threatened, porcupines may raise their quills and make loud hissing or growling noises as a warning. They are primarily herbivores, feeding on a diet of plants, bark, and leaves. Porcupines are known for their excellent climbing and tree-dwelling abilities, using their sharp claws and prehensile tails to navigate the treetops. Despite their spiky appearance, porcupines are generally not aggressive towards humans and prefer to use their quills as a defensive mechanism rather than actively attacking.
