Gaur
Natural predators

Due to their size and power, gaur have few natural predators besides humans. Leopards, dhole packs and large mugger crocodiles occasionally attack unguarded calves or unhealthy animals. Only tigers and saltwater crocodiles have been reported to kill adult gaur. However, the habitat and distribution of the gaur and saltwater crocodile seldom overlap in recent times, due to the decreasing range of both species. A crocodile likely would need to be a mature adult male (more than 3.7 m or 12 ft and 300 kg or 660 lb) to make a successful attack on healthy adult gaurs.

Tigers hunt young or infirm gaur, but have also been reported to have killed healthy bulls weighing at least 1,000 kg (2,200 lb). When confronted by a tiger, the adult members of a gaur herd often form a circle surrounding the vulnerable young and calves, shielding them from the big cat. As tigers rely on ambush attacks when taking on prey as large as a gaur, they will almost always abandon a hunt if detected and met in this manner. A herd of gaur in Malaysia encircled a calf killed by a tiger and prevented it from approaching the carcass. Nevertheless, the gaur are formidable opponents to the tigers, and they are capable of killing tigers in self-defence.
