The Cape porcupine or South African porcupine, (''Hystrix africaeaustralis''), is a species of Old World porcupine native to central and southern Africa. ==Description== Cape porcupines are the largest rodents in southern Africa and also the world's largest porcupines. They are similar in appearance to, and only slightly larger than, their close relatives, the crested porcupines, and can most easily be distinguished from them by the presence of a band of short white spines along the midline of the rump. Cape porcupines measure long from the head to the base of the tail, with the tail adding a further . They weigh from , with exceptionally large specimens weighing up to ;〔Burnie D and Wilson DE (Eds.), ''Animal: The Definitive Visual Guide to the World's Wildlife''. DK Adult (2005), ISBN 0789477645〕〔(Wildcliff Nature Reserve )〕 males and females are not significantly different in size.〔 They are heavily built animals, with stocky bodies, short limbs, and an inconspicuous tail. The body is covered in long spines up to in length, interspersed with thicker, sharply pointed, defence quills up to long, and with bristly, blackish or brownish fur. The spines on the tail are hollow, and used to make a rattling sound to scare away predators. An erectile crest of long, bristly hairs runs from the top of the head down to the shoulders. The spines and quills cover the back and flanks of the animal, starting about a third of the way down the body, and continuing onto the tail. The quills have multiple bands of black and white along their length, and grow from regularly spaced grooves along the animal's body; each groove holding five to eight quills. The remainder of the animal, including the undersides, is covered with dark hair.〔 The eyes and ears are relatively small, and the mobile whiskers are short. The feet have five clawed toes, although the first toes on the forefeet are vestigial. Females have two pairs of teats.〔
