The black-backed jackal is a fox-like canid [8] with a slender body, long legs, and large ears. [9] It is similar to the closely related side-striped jackal and more distantly related to the golden jackal , though its skull and dentition are more robust and the incisors much sharper. [ 8 ]
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.
When there is a change in the weather, jackals will produce a long and continuous chorus. [102] Dominant canids defend their territories against intruders with either a howl to warn them off, approach and confront them, or howl followed by an approach. Jackals, wolves and coyotes will always approach a source of howling. [104]
Golden jackals have since increased greatly in number year by year, with some estimates indicating that they now outnumber red foxes. The sighting of a jackal near the Austrian border in the summer of 2007 indicated that they have spread throughout the country. [36] [37] There have been repeated sightings of jackals in eastern Austria for a few ...

Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years. [2]
The Egyptian wolf had an unresolved taxonomic identity and was formerly known as the Egyptian jackal. Throughout much of the 20th century, the animal was classed as a subspecies of golden jackal, Canis aureus lupaster. Notice was however taken by numerous zoologists of the animal's morphology, which corresponds more to that of the grey wolf.
