A tiger will think twice before attacking this animal, even though it is alone. Which is it ?

The tiger (Panthera tigris) is the largest cat species, reaching a total body length of up to 3.38 m (11.1 ft) over curves and weighing up to 388.7 kg (857 lb) in the wild. Its most recognizable feature is a pattern of dark vertical stripes on reddish-orange fur with a lighter underside. The species is classified in the genus Panthera with the lion, leopard, jaguar and snow leopard. Tigers are apex predators, primarily preying on ungulates such as deer and bovids.  The wild  buffalo (Bubalus arnee), also called Asian buffalo and Asiatic buffalo, is a large bovine native to the Indian Subcontinent and Southeast Asia.
Tigers will be mostly killed by wild buffaloes, when they both fight. So, a tiger will have to think twice before attacking wild buffalo.
