Golden jackal
The golden jackal is similar to the gray wolf but is distinguished by its smaller size, lighter weight, more elongated torso, less-prominent forehead, shorter legs and tail, and a muzzle that is narrower and more pointed. The legs are long in relation to its body, and the feet are slender with small pads. Males measure in body length and females . Males weigh and females weigh . The shoulder height is for both. In comparison, the smallest wolf is the Arabian wolf ("Canis lupus arabs"), which weighs on average .

Results from two recent studies of mDNA from golden jackals indicate that the specimens from Africa are genetically closer to the gray wolf than are the specimens from Eurasia. In 2015 a major DNA study of golden jackals concluded that the six "C.aureus" subspecies found in Africa should be reclassified under the new species "C.anthus" (African golden wolf), reducing the number of golden jackal subspecies to seven. The phylogenetic tree generated from this study shows the golden jackal diverging from the wolf/coyote lineage 1.9million years ago and the African golden wolf diverging 1.3million years ago. The study found that the golden jackal and the African golden wolf shared a very similar skull and body morphology and that this had confused taxonomists into regarding these as one species. The study proposes that the very similar skull and body morphology is due to both species having originated from a larger common ancestor.
