The Southern African hedgehog (Atelerix frontalis) is a species of mammal in the family Erinaceidae. It is found in Angola, Botswana, Lesotho, Namibia, South Africa, Tanzania and Zimbabwe.
Their bodies are covered by sharp spines. The average mass of a fully grown male is 350g. The main color is brown but there are other colors too. A Southern African hedgehog is covered with spines all over its body except for its face, belly and ears, and these spines are made of keratin protein with a hollow shaft and a muscle for each spine. These unprotected body parts are covered with fur. They are dark brown and their spines are typically white at the base and dark brown at the tip. They have pointed snouts and typically have either a white or brown belly. The average length of the hedgehog is approximately 20 cm. The main characteristic of this type of hedgehog is that they have a white stripe across their forehead, typically, traveling from one leg to the other.
The Southern African hedgehog is said to be a slow mover; however, when threatened, it can move surprisingly fast at 6 to 7 kilometers/hour. During the day, they typically stay where they live, which is an area that is covered with vegetation or in a hole in the ground. When the hedgehog rests, it curls up into a ball. Night time is when the hedgehog forages for food, making it nocturnal. The Southern African hedgehog hibernates during the winter and studies show that heterothermy helps keep the energy balance for this species during winter.
Their protective mechanism is to curl into a ball when threatened. This, however, is not always enough defence against the powerful claws and hard feet of predatory birds, such as owls.
The gestation period is one month with a litter of between one and nine newborns. Mating season for the Southern African hedgehog is typically in the summer. With a gestation period of around 35 days, the babies are mainly born during the months of October through March. The size of the litters range from 1 to 11 babies with an average of four young. A newborn hedgehog typically weighs around 10g. The young are naked and blind when they are born and are born with infant spines, which are typically shed by the young when they are a month old. The next set of spines that are grown are their adult spines. The amount of time it takes until a baby begins to forage with its mother is about 6 weeks and they will open their eyes about 2 weeks after birth. Hedgehogs can breed multiple times in one year and the baby hedgehogs reach sexual maturity 61–68 weeks of age. Males take no part in the raising of the young.
