“jackal”的意思、由来-百科全书

jackal

mammal

any of several species of wolflike carnivores of the dog genus Canis, family Canidae, sharing with the hyena an exaggerated reputation for cowardice. Three species are usually recognized: the golden, or Asiatic, jackal (C. aureus), found from eastern Europe and northeast Africa to Southeast Asia, and the black-backed (C. mesomelas) and side-striped (C. adustus) jackals of southern and eastern Africa. Jackals grow to a length of about 85–95 cm (34–37 inches), including the 30–35-centimetre (12–14-inch) tail, and weigh about 7–11 kg (15–24 pounds). The golden jackal is yellowish; the black-backed jackal is rusty red with a black back; and the side-striped jackal is grayish with a white-tipped tail and an indistinct stripe on each side.

Jackals inhabit open country. They are nocturnal animals that usually conceal themselves by day in brush or thickets and sally forth at dusk to hunt. They live alone, in pairs, or in packs and feed on whatever small animals, plant material, or carrion is available. They follow lions and other large cats in order to finish a carcass when the larger animal has eaten its fill. When hunting in packs, they are able to bring down prey as large as an antelope or sheep.

Like other members of the genus, jackals sing at evening; their cry is considered more dismaying to human ears than that of the hyena. They have an offensive odour caused by the secretion of a gland at the base of the tail. The young are born in burrows, the litters containing two to seven pups; gestation lasts 57 to 70 days. Like wolves and coyotes, jackals interbreed with domestic dogs.

The aardwolf (q.v.), family Hyaenidae, is sometimes called a maned, or gray, jackal. The South American fox (q.v.), Dusicyon, is sometimes referred to as a jackal.
