The Crested Porcupine lives in savannas, steppes, open woodlands, highlands, gallery forests, forest edges and semi-deserts. It is not found in deserts and rainforests.
The Crested Porcupine has long, black, and white spines of about 50 centimeters. It uses these to scare off possible enemies by producing a rattling sound with these spines. The small capsules on its short tail also make a rattling sound during danger.
