The aardwolf (Proteles cristatus) is an African carnivorous mammal of the family Hyaenidae. The aardwolf, whose name in Afrikaans means 'earth wolf', resembles a small striped hyena. It is yellowish with vertical black stripes and a bushy, black-tipped tail, and it bears a long, coarse mane of erectile hairs along the length of its back. The aardwolf lives on the open, grassy plains of southern and eastern Africa. The aardwolf feeds largely on termites, particularly on the species Trinervitermes trinervoides. It is nocturnal, lives in a burrow, and is usually solitary but may forage in small packs. The litter generally consists of three or four young. The aardwolf is harmless and shy; when attacked, by dogs for example, it emits a musky-smelling fluid and may fight. Research Aardwolf
The Hyena is an African carnivore, of the family Hyaenidae. It has a large head and neck, long, well-developed forelegs, and powerful jaws and premolars adapted for crushing bones. Each foot has four toes with non-retractable claws, well suited for running on the open plains where hyenas feed on hoofed animals. Of the three hyena species, the best known is the spotted, or laughing, hyena (Crocuta crocuta) , the only member of its genus. Ranging south of the Sahara, it is the largest and most robust of the hyenas, with a length of 1.8 m and a height of 90 centimetres at the shoulder. Adults are brown-grey with dark brown or black spots. Named for their cry, which has been compared to hysterical human laughter, they also emit a striking howl that rises in pitch. Spotted hyenas were long thought to be only scavengers (warring African tribes abandoned their dead to the animal). Recently, hyenas have been found to be among the chief predators of herbivores, especially zebra and wildebeest.
The hyenas attack in packs at night, ripping open the flanks of their prey and carrying off the carcasses. Hyenas associate in clans cantered around communal dens occupied by batches of young at varying stages of growth. Females conceive throughout the year, giving birth after 110 days to one or two cubs, which dig their own tunnels. Pair bonding is not evident; the female, larger than the male, selects her mating partners. The female sexual organs have an external resemblance to the male's, a phenomenon probably related to scent identification, which plays a large part when clan members encounter one another.
A clan may consist of ten or twelve females, twenty cubs, and a number of males on the fringe; hyenas are very territorial. Little is known about the genus Hyaena , which comprises the striped hyena, Hyaena Hyaena , and the brown hyena, Hyena brunnea. Both bear manes of coarse, erectile hair and are smaller and far less aggressive than the spotted hyena. The striped hyena, grey-tan with vertical stripes, ranges from East Africa north into Asia. It is largely a scavenger, often eating vulture-picked bones. The brown hyena, found in southern Africa, is dark brown with a grey head and striped legs. It feeds mainly on fish and crabs.
