The family Nandiniidae includes just a single species, the nocturnal, arboreal, mainly solitary, and somewhat secretive African Palm Civet (Nandinia binotata). African Palm Civets are among the most common small carnivores in forested regions throughout much of tropical Africa, although they are threatened by both habitat destruction and hunting by humans for food, traditional medicine, and fur for decorative uses (they are the most commonly sold carnivores in markets in Equatorial Guinea and Guinea), as well as to protect crops and poultry. They are found in rain forests and deciduous forests in West and Central Africa from Gambia to southwest Sudan and can also be found in some regions with montane and subtropical forest in northern Angola and eastern and southeastern Africa. They are common in coastal lowland forests and their range extends into montane forest as high as 2500 meters in both West Africa (Cameroon) and East Africa (Tanzania). In addition to rain forests, African Palm Civets are found in riparian forest, deciduous woodland, and savannah woodland, occurring not only in undisturbed forest but also in secondary forest and other disturbed woodlands.
At one time African Palm Civets were placed in the family Viverridae. By the mid-20th century, however, the species was moved to its own family based on several very distinctive morphological features, a taxonomic judgement that has been supported by subsequent phylogenetic analysis based on both molecular and morphological data (e.g., Eizirik et al. 2010).
African Palm Civets feed mainly on fruit, but also take some animal prey such as insects, bird eggs and nestlings, small rodents, and even carrion.
In parts of their range, African Palm Civets are sometimes kept as pets.

The family Nandiniidae contains just one genus and species, Nandinia binotata, the African palm civet.
African palm civets are distributed across sub-Saharan Africa, from southern Sudan to Guinea-Bissau and southward to eastern Zimbabwe and northern Angola.
Biogeographic Regions: ethiopian (Native )
African palm civets are small, muscular carnivores, with powerful limbs and long, sturdy tails suited to agility in the treetops. These animals range in length from 440 to 580 mm, with the tail adding another 460 to 620 mm. Weight ranges from 1.7 to 5 kg, with males at the high end of this range. African palm civets have short, round ears and yellow eyes with pupils that narrow to a slit in sunlight. The claws are sharp, curved, and fully retractile. The soft, woolly coat gives these animals protection from the elements and the coloration provides camouflage: it is gray or brown and mottled with darker brown on the lower back, and the underparts are grayish-yellow. The tail is darker than the body and ringed with black. There are scent glands between the toes, on the palms, on the abdomen, and possibly on the chin.
Nandinia can be set apart from other living feliform taxa by the primitive condition of its basicranium and auditory bulla. The bulla is not inflated and is single-chambered, and the paroccipital process is directed caudally and does not contact the bulla. Also, the caudal entotympanic is cartilaginous, which is a feature unknown in any other living carnivore.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
African palm civets are forest-dwelling mammals that spend the majority of their time in trees. Occasionally they cross open areas in search of food.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: forest
African palm civets are omnivores, with fruit making up the largest portion of their diet. They also feed on small mammals, birds, bird eggs, and insects. They primarily forage in trees, but may also search for fallen fruit on the forest floor. African palm civets do not attack active birds and mammals, preferring to capture these larger prey animals when they are sleeping. They hold their prey steady with their forearms while they deliver a quick series of killing bites, after which they may swallow their food whole.
Primary Diet: omnivore
African palm civets are primary and higher-level consumers, because they eat both fruit and animals. They are also prey themselves for raptors, pythons, and leopards.
Potential predators of African palm civets include diurnal raptors, pythons, and leopards. African palm civets avoid predation through cryptic coloration and agility in the trees.
- diurnal raptors (Accipitridae)
- pythons (Python)
- leopards (Panthera pardus)
Anti-predator Adaptations: cryptic
Life History and Behavior
African palm civets sense visual, chemical, auditory, and tactile stimuli, as do other carnivores. Olfaction is particularly well-developed, and scent is the primary means of communication. Glands on the palms and between the toes leave scent trails when these animals walk along branches. Individuals have been observed rubbing their chins on tree bark, either to pick up scents from others or to leave their own. A strong-smelling brown secretion is produced by an area of glandular skin on the lower abdomen; this is also used for scent-marking. In addition, females have scent glands in the skin overlaying the mammary glands. Secretions from these scent glands stain the fur of the belly a bright orange-yellow and rub off on the nursing young. This scent appears to repel sexual approaches by males and perhaps neutralizes attacks on the young. African palm civets also communicate through vocalizations. Males and females cry out during courtship, and females "meow" to call their young. Nursing young purr like cats, a possible tactile form of communication.
Communication Channels: tactile ; acoustic ; chemical
Other Communication Modes: scent marks
Perception Channels: visual ; tactile ; acoustic ; chemical
The typical lifespan of wild African palm civets is not known. A longevity record of 15.8 years has been established in captivity.
The mating system of African palm civets has not been reported, but they are presumed to be polygynous based on the fact that one adult male territory usually overlaps several adult female territories. Both males and females have been heard emitting loud cries during courtship.
Mating System: polygynous
African palm civets breed year round, with peak births in May and October. The gestation period is 64 days. Usually there are two young per litter, but litters of up to four have been reported. These animals reach sexual maturity at three years of age.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Like all eutherian mammals, female African palm civets nourish their young through the placenta before giving birth, and then with milk afterwards. Males make no investment in their offspring besides providing sperm. For bearing young, females seek out arboreal shelters such as tree hollows. Age to weaning has not been reported, but it is known that male offspring leave their mothers' territories immediately afterward. Young females may remain somewhat longer.
Parental Investment: pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Protecting: Female); post-independence association with parents

Nandinia is classified as lower risk by the IUCN. African palm civets are still common and widespread.
Relevance to Humans and Ecosystems
Palm civets frequent chicken coops and steal roosting poultry.
Humans occasionally tame African palm civets and keep them in their homes to control rodents and cockroaches.
