While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of 16 km/h (10 mph) for extended periods of time. Jackals are crepuscular, most active at dawn and dusk.
Their most common social unit is a monogamous pair, which defends its territory from other pairs by vigorously chasing intruders and marking landmarks around the territory with their urine and feces. The territory may be large enough to hold some young adults, which stay with their parents until they establish their own territories. Jackals may occasionally assemble in small packs, for example, to scavenge a carcass, but they normally hunt either alone or in pairs.
Etymology
The English word jackal dates back to 1600 and derives from French chacal, itself from Ottoman Turkish چقال (çakal), itself from Persian شغال (shaghāl), from or cognate with Ancient Sanskrit शृगाल (śṛgāla-), meaning 'the howler'.

Taxonomy and relationships
Similarities between jackals and coyotes led Lorenz Oken, in the third volume of his Lehrbuch der Naturgeschichte (1815), to place these species into a new separate genus, Thos, named after the classical Greek word θώς "jackal", but his theory had little immediate impact on taxonomy at the time. Angel Cabrera, in his 1932 monograph on the mammals of Morocco, questioned 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 that genus. In practice, Cabrera chose the undivided-genus alternative and referred to the jackals as Canis instead of Thos.
Oken's Thos theory was revived in 1914 by Edmund Heller, who embraced the separate genus theory. Heller's names and the designations he gave to various jackal species and subspecies live on in current taxonomy, although the genus has been changed from Thos to Canis.
The wolf-like canids are a group of large carnivores that are genetically closely related. They all have 78 chromosomes. The group includes genus Canis, Cuon, and Lycaon. The members are the dog (C. lupus familiaris), gray wolf (C. lupus), coyote (C. latrans), golden jackal (C. aureus), Ethiopian wolf (C. simensis), black-backed jackal (C. mesomelas), side-striped jackal (C. adustus), dhole (Cuon alpinus), and African wild dog (Lycaon pictus). The latest recognized member is the African wolf (C. lupaster), which was once thought to be an African branch of the golden jackal. As they possess 78 chromosomes, all members of the genus Canis are karyologically indistinguishable from each other, and from the dhole and the African hunting dog. The two African jackals are shown to be the most basal members of this clade, indicating the clade's origin from Africa. Canis arnensis arrived in Mediterranean Europe 1.9 million years ago and is probably the ancestor of modern jackals.
The paraphyletic nature of Canis with respect to Lycaon and Cuon has led to suggestions that the two African jackals should be assigned to different genera, Schaeffia for the side-striped jackal and Lupulella for the black-backed jackal or Lupulella for both.
The intermediate size and shape of the Ethiopian wolf has at times led it to be regarded as a jackal, thus it has also been called the "red jackal" or the "Simien jackal".
Species
Folklore and literature
In the Indian Panchatantra stories, the jackal is mentioned as wily and wise. In Bengali tantrik tradition, they represent the goddess Kali. It is said she appears as jackals when meat is offered to her.
The canid which Anubis was modeled upon has frequently been stated to have been the golden jackal, though the African variant of this animal present in Egypt was reclassified in 2015 as a separate species now known as the African wolf, which was found to be more closely related to wolves and coyotes than to the jackal. Some authors have opined that Anubis is more probably modeled after a fox or Ethiopian wolf. Nevertheless, ancient Greek texts about Anubis consistently refer to the deity as having the head of a dog rather than that of any wild canid, and there is still uncertainty as to what species represents Anubis.
The Serer religion and creation myth posits jackals were among the first animals created by Roog, the supreme deity of the Serer people.
Like foxes and coyotes, jackals are often depicted as clever sorcerers in the myths and legends of their regions. They are mentioned roughly 14 times in the Bible. It is frequently used as a literary device to illustrate desolation, loneliness, and abandonment, with reference to its habit of living in the ruins of former cities and other areas abandoned by humans. It is called "wild dog" in several translations of the Bible. In the King James Bible, Isaiah 13:21 refers to 'doleful creatures', which some commentators suggest are either jackals or hyenas. Additionally, the biblical character Job is known to have suffered tremendous loss and death, and in Job 30:29 he laments his situation by associating himself to be "a brother of jackals."
In Nonviolent Communication (NVC) the Jackal is used to represent one's inner judgmental voice. The Jackal represents inner thoughts and stories about others and ourselves. Marshall Rosenberg, the father of NVC, said that he came up with the metaphor of the Jackal when traveling in Europe and one of his workshop participants were complaining about her husband when Marshall asked "are you still dealing with that old jackal?". Since then he routinely used the Jackal to present the counterpart to the nonviolent giraffe in NVC.
