The Cape porcupine (Hystrix africaeaustralis), Cape crested porcupine or South African porcupine, is a species of Old World porcupine native to central and southern Africa.
Description
Cape porcupines are the largest rodents in Africa and also the world's largest porcupines. Cape porcupines are amongst the largest living rodents in the world; a few other rodents appear to be larger in body mass such as the
Cape porcupines measure 63 to 81 centimetres (25 to 32 inches) long from the head to the base of the tail, with the tail adding a further 11–20 centimetres (4.3–7.9 inches).[2] They weigh from 10 to 24 kilograms (22 to 53 pounds), with exceptionally large specimens weighing up to 30 kg (66 lb);[7][8] males and females are not significantly different in size.[2] The average weight of males from Zimbabwe was 16.9 kg (37 lb) and while the average for females there was 18.4 kg (41 lb) while in the Orange river valley of South Africa males averaged 12.3 kg (27 lb) and females averaged 13 kg (29 lb).[2]
They are heavily-built animals, with stocky bodies, short limbs, and an inconspicuous tail. The body is covered in long spines up to 50 centimetres (20 in) in length, interspersed with thicker, sharply pointed, defence quills up to 30 centimetres (12 in) 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
The eyes and ears are relatively small, and the mobile
Distribution and habitat
Cape porcupines are found across the whole of southern and central Africa, to southern Kenya, Uganda, and Congo at the northern edge of their range. They inhabit a wide range of habitats, from sea level to 2,000 metres (6,600 ft), although they are only marginally present in dense forests and the driest of deserts, and are not found in swampland.[1][9] There are no currently recognised subspecies.
Diet and behaviour
Cape porcupines eat mostly plant material: fruits, roots, tubers, bulbs, and bark. They have a long

When attacked, the porcupine freezes. If cornered, it turns vicious and charges to stab its attacker with its quills. Otherwise, the porcupine may retreat into its burrow, exposing only its quills and making it hard to dislodge.
Reproduction
Cape porcupines mate throughout the year, although births are most common during the rainy season, between August and March. Unless a previous litter is lost, females typically give birth only once each year.
Gestation lasts around 94 days, and results in the birth of a litter of up to three young, although over half of births are of singletons.[14] Newborn young weigh 300 to 440 grams (11 to 16 oz), and initially have soft quills. Although they are born with their incisor teeth fully erupted, the remaining teeth begin to appear at 14 days, with the full set of adult teeth present by 25 months.[16] They are weaned at around 100 days of age,[14] and grow rapidly for the first twenty weeks, reaching the full adult size, and sexual maturity, at the end of their first year.[17]
Relative to most other rodents, Cape porcupines are long-lived, surviving for ten years in the wild, or up to twenty years in captivity.[2]
