European jackal
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
Golden jackal
The biological family "Canidae" is composed of the South American canids, the fox-like canids, and the wolf-like canids. All species within the wolf-like canids share a similar morphology and possess 78chromosomes, allowing them potentially to interbreed. Within the wolf-like canids is the jackal group, which includes the three jackals: the black-backed jackal ("C.mesomelas"), the side-striped jackal ("Canis adustus"), and the golden jackal ("Canis aureus"). These three species are approximately the same size, possess similar dental and skeletal morphology, and are identified from each other primarily by their coat color. They were once thought to have different distributions across Africa with their ranges overlapping in East Africa (Ethiopia, Kenya, and Tanzania). Although the jackal group has traditionally been considered as homogenous, genetic studies show that jackals are not monophyletic (they do not share a common ancestor), and they are only distantly related. The accuracy of the colloquial name "jackal" to describe all jackals is therefore questionable.
