I have put 3 links below which have some photos of the Wild Buffalo. This animal is not the same as the ferral buffalo found in Australia. The Wild buffalo is over 6 feet tall at the shoulder & weighs up to 1200 kgs. It is actually a lean looking animal with long legs. It is twice as big as the domestic or ferral buffalo.

In temperament they are extreamly volatile & agressive. Every year game rangers & locals are killed by wild buffalo in the national parks of Assam state in Eastern India. They are known to charge tame riding elephants with tourists riding the elphants!! Tigers will rarely take a calf. They are known to take rhino calves more often than buffalo calves.

It is difficult to compare them with the African buffalo as there are so few of them left. They are probably equally dangerous but the Asian wild buffalo is a swamp dwelling animal & is likely to give you a bit more time. In terms of agression & temperament I doubt if we could tell the difference.

My favourite of the wild cattle is the giant Gaur - the Indian "bison". This is the most handsome of wild cattle. Standing over 6 feet & 1200 kgs, the jet black bulls have the white stocking & rippling muscles. I have seen them many, many times and never tire of it! They are not reputed to be particularly agressive though a cow will defend its calf with her life.
