स्याल एक वन्यजन्तु हो, जुन साधारणतयाअफ्रिका,एसिया र दक्षिण पूर्वीयुरोपमा पाइन्छ।स्यालको लामा खुट्टा रको मद्दतले यसले साना तथा हरूको शिकार गर्ने गर्छ। साथै ठूला खुट्टा र मजबुत तथा लचकदार हाडले बनेको शारीरिक संरचनाले गर्दा यिनीहरू लामो दुरी सजिलै पार गर्ने गर्छन। स्याल १६ कि.मि. प्रति घन्टाको दरले दौडन सक्दछ। स्याल सामान्यतया मिर्मिरे बिहान तथा गोधुली सांझमा सक्रिय हुने जनावर हो।
स्यालहरू जोडीमा आ-आफ्नो छुट्टा छुट्टै क्षेत्रमा बस्ने गर्छन, यिनीहरूले आ-आफ्नो क्षेत्रको सिमाना दिशा वा पिशाबको मद्दतले छुट्याउने गर्दछन। स्यालको बच्चा जन्मिइ ठूलो भएर आफ्नो क्षेत्र बनाई नबसे सम्म यिनीहरू आफ्नो आमाबाबु संगै एउटै क्षेत्रमा नै बस्ने भएकोले यिनीहरूको क्षेत्र ठूलो हुने गर्छ। स्यालहरू कहिलेकांही झुण्डमा पनि बस्ने गर्छन, तापनि स्यालले शिकार गर्दा भने एक्लै वा जोडीमा गर्ने गर्दछ।

प्रजातीहरू[सम्पादन गर्ने]
| Species | Trinomial authority | Description | Range |
|---|---|---|---|
| Side-striped jackal Canis adustus 
|
Sundevall, 1847 | Primarily resides in wooded areas, unlike other jackal species. It is the least aggressive of the jackals, rarely preying on large mammals.[१] | Central and southern Africa |
| Golden jackal Canis aureus .jpg)
|
Linnaeus, 1758 | The heaviest of the jackals, and the only species to subsist outside of Africa. Although often grouped with the other jackals, genetic and morphological research indicates that the golden jackal is more closely related to the gray wolf and the coyote.[२][३] | Northern Africa, Southeastern Europe, the Middle East, Western Asia, and South Asia |
| Black-backed jackal Canis mesomelas
|
Schreber, 1775 | The most lightly-built jackal, this is considered to be the oldest living member of the genus Canis.[४] It is the most aggressive of the jackals, having been known to attack animal prey many times its own weight, and it has more quarrelsome intra-pack relationships[५] | Southern Africa and eastern coast of Kenya, Somalia, and Ethiopia |
The Ethiopian wolf (Ruppell, १८४०) of the Ethiopian highlands has at times been regarded as a jackal, hence were called the "red jackal" or the "simian jackal", but these are now usually classified as wolves.
