Black-backed jackal Lupulella mesomelas. Schreber, 1775 The most lightly built jackal, once considered to be the oldest living member of the genus Canis, [13] it is now placed in the genus Lupulella. It is the most aggressive of the jackals, being known to attack animal prey many times its own weight, and it has more quarrelsome intrapack ...
The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis, such as the promotion of the African golden wolf to a separate species from the golden jackal, and splitting out the Lupulella genus from Canis ...

The jackal-sized Eucyon existed in North America from 10 million YBP and by the Early Pliocene about 6-5 million YBP the coyote-like Eucyon davisi [13] invaded Eurasia. The canids that had emigrated from North America to Eurasia – Eucyon , Vulpes , and Nyctereutes – were small to medium-sized predators during the Late Miocene and Early ...
The black-backed jackal is a monogamous and territorial animal, whose social organisation greatly resembles that of the golden jackal. However, the assistance of elder offspring in helping raise the pups of their parents has a greater bearing on pup survival rates than in the latter species. [ 10 ]
If the animals are truly settled in an area, they would howl in back at the recordings to mark their territory; however, as of 2019, this had never occurred. The presence of the animal has proven much less sensational than the return of the wolf. [48] A golden jackal was photographed in late 2017 in Haute-Savoie, southeastern France. [49]
In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group recommends that because DNA evidence shows the side-striped jackal (Canis adustus) and black-backed jackal (Canis mesomelas) to form a monophyletic lineage that sits outside of the Canis/Cuon/Lycaon clade, that they should be placed in a distinct genus, Lupulella (Hilzheimer ...
The side-striped jackal is a slender, medium-sized canid, which tends to be slightly larger on average than the black-backed jackal. Body mass ranges from 6.5 to 14 kg (14 to 31 lb), head-and-body length from 69 to 81 cm (27 to 32 in) and tail length from 30 to 41 cm (12 to 16 in). [16]
