A jackal (from Turkish çakal, via Persian shaghal ultimately from Sanskrit sṛgālaḥ American Heritage Dictionary - Jackal entryOnline Etymology Dictionary - Jackal entry) is any of three (sometimes four) small to medium-sized members of the family Canidae, found in Africa, Asia and Southeastern Europe.Ivory, A. 1999. "Canis aureus" (On-line), Animal Diversity Web. Accessed January 18, 2007 at http://animaldiversity.ummz.umich.edu/site/accounts/information/Canis_aureus.html. Jackals fill a similar ecological niche to the coyote in North America, that of predators of small to medium-sized animals, scavengers, and omnivores. Their long legs and curved canine teeth are adapted for hunting small mammals, birds and reptiles. Big feet and fused leg bones give them a long-distance runner\'s physique, capable of maintaining speeds of 16km/h (10mph) (just over 6 min/mile) for extended periods of time. They are nocturnal, most active at dawn and dusk.

In jackal society the social unit is that of a monogamous pair which defends its territory from other pairs. These territories are defended by vigorously chasing intruding rivals and marking landmarks around the territory with urine and feces. The territory may be large enough to hold some young adults who stay with their parents until they establish their own territory. Jackals may occasionally assemble in small packs, for example to scavenge a carcass, but normally hunt alone or as a pair.

Jackals are considered close to what all ancestral canids looked and behaved like. Despite their outward similarity, these species are not considered closely related to one another. The Simian Jackal is actually a wolf that is thought to have taken on the appearance of a large fox or jackal through convergent evolution (by adopting a similar diet of small rodents), and the other three \'true jackals\' are believed to have split from each other 6 mya. The Golden Jackal is thought to have evolved in Asia whilst the other two species evolved in Africa.

Species:

• Golden Jackal (Canis aureus)
• Side-striped Jackal (Canis adustus)
• Black-backed Jackal (Canis mesomelas)

The Ethiopian Wolf (Canis simensis) is sometimes called the Red or Simian Jackal, but is more closely related to the wolves.

Genus controversy

In 1816 in the third volume of Lorenz Oken’s Lehrbuch der Naturgeschichte, the author found sufficient similarities in the dentition of jackals and the North American coyotes to place these species into a new separate genus Thos after the classical Greek word θώς. Oken’s idiosycratic nomenclatorial ways however, aroused the scorn of a number of zoological systematists. Nearly all the descriptive words used to justify the genus division were relative terms without a reference measure and that the argument did not take into account the size differences between the species which can be considerable. Angel Cabrera, in his 1932 monograph on the mammals of Morocco, briefly touched upon the question whether or not the presence of a cingulum on the upper molars of the jackals and its corresponding absence in the rest of Canis could justify a subdivision of the genus Canis. In practice, he chose the undivided-genus alternative and referred to the jackals as Canis.

Oken’s Thos theory had little immediate impact on taxonomy and/or taxonomic nomenclature, though it was revived in 1914 by Edmund Heller who embraced the new genus theory. Heller’s name and the designations he gave to various jackal species and subspecies live on, though the genus has changed been changed from Thos to Canis.http://www.holgerhomann.us/Thos_vs%20%20Canis.htm

Ancient use

The Ancient Egyptian god of embalming and the underworld, Anubis, was depicted as a man with a jackal\'s head. Today they are one of the more commonly seen animals on safaris, and are found outside of national parks and do well in human altered landscapes and even near and in human settlements.

Use in slang

A Golden Jackal

All species of jackal are capable predators (all three hunt rodents and small mammals regularly, with the Golden and Black-backed species known to hunt poisonous snakes, large ground birds such as bustards, and mammals as large as young antelope). However, their popular image as scavengers has resulted in a negative public image.

• The expression "jackalling"" is sometimes used to describe the work done by a subordinate to save the time of a superior. (For example, a junior lawyer may peruse large quantities of material on behalf of a barrister.) This came from the tradition that the jackal will sometimes lead a lion to its prey. In other languages, the same word is sometimes used to describe the behaviour of persons who try to scavenge scraps from the misfortunes of others; for example. by looting a village from which the inhabitants have fled because of a disaster.
• In Nonviolent Communication, "jackal language" refers to communication that labels, judges, and criticizes.
