Scientific Name: Atelerix frontalis
Common Name: Hedgehog, Kap-Igel, Riccio, Krimpvarkie,
Le Herisson du Cap, Erizo, Fikifa
Description: Short, strong sharp spines cover
the whole of the back and sides from the forehead to the rump. Each spine
is a thick, stiff hair, about 2cm long, white/cream-coloured at the base,
black or dark brown in the middle, and white or buff at the tip. Some spines
are white, and form broad bands along the back. The face, legs, tail and
underside are covered with dark-coloured hair, dark or grey-brown on the
face, legs and tail; black, white or a combination on the underside. A
clear white band runs across the forehead. The snout is pointed, the ears
are small and the tail is short. There are five toes on each foot. Hedgehogs
have long legs and can move surprisingly fast.
Difference in Sex: Females have two pairs
of nipples on the chest and a pair on the belly.
Average Weight: 240-400
g
Habitat: A wide variety of habitats although they
do not occur in desert and high-rainfall areas. They prefer semi- arid
and sub-temperate areas with between 300 and 800 mm rain per year.
Habits: Hedgehogs are mostly nocturnal, resting
in dense vegetation under debris, under logs, or burrows. Semi-permanent
resting sites used only by females with young or during winter. May be
seen in daytime during the rainy season. They are solitary, encounters
are noisy with much snuffling and snorting and head butting. Hedgehogs
move slowly when foraging but can run at 7 km/h. Prey is found by
smell and is rooted out from litter and under rocks and logs. They are
noisy and rely more on the spines than concealment for protection against
predators. When disturbed they curl up and pull the spiny skin on its back
down over its head and legs to form a ball of spines. When temperatures
are low, day length is under 11 hours, or food availability is low, they
become inactive. When such conditions get worse, extended periods of inactivity
result.
Main feeding time: Nocturnal but do come out during
the day when it start raining.
Size: Head and body length 18 cm; tail 2 cm
Gestation: Breeds during summer months. Gestation
is 35 days and there are usually 3-4 in a litter. Newborn young are blind
and naked and only the tips of the spines can be seen. The spines grow
through the skin 1-3 hours after birth and are are replaced at 4-6 weeks
at which time the young begin to forage with their mother. Young are weaned
at 5 weeks and are independent at 6-7 weeks.
Number of young at birth: 3 to 4 young
Communication: Sniffing, growling and snorting.
The alarm call is a high-pitched screech
Age: 8 to 10 years
Diet: Mainly insects but also small rodents,
eggs, frogs, earthworms and vegetable matter. Water-independent.
Enemies: Despite the spines which provide protection
against other carnivores, Giant eagle owls (Bubo lacteus) eat hedgehogs
in large numbers.
