The term 'fox or jackal' refers to two species of canines. The fox is a small, omnivorous mammal belonging to the family Canidae, while the jackal is a medium-sized CANINE found in Africa, Asia, and southeastern Europe. Both animals are members of the same biological family, but they differ in size, habitat, and diet. Foxes are typically found in wooded areas, while jackals are more commonly found in open grasslands and deserts. Foxes are omnivorous, eating both plants and animals, while jackals are primarily carnivorous, feeding on small mammals, birds, reptiles, and insects.
