A genus of large rodents commonly known as porcupines, native to North and South America.
From Greek 'erethizein' meaning 'to irritate' or 'to wound,' referencing the animals' spiky quills that irritate anything they contact. The scientific name perfectly captures the creature's defensive mechanism.
Scientists named the porcupine genus after its most famous feature—irritation—showing how even scientific Latin reveals an animal's most memorable characteristic and its impact on humans who encountered it.
