Gaur are said to look like water buffalo at the front and domestic cattle at the back. They are the heaviest and most powerful of all wild cattle, and are among the largest living land animals; only elephants, rhinos and hippos consistantly grow larger, and the weight of guar may equal or even surpass that of a giraffe. Males have highly muscular bodies, with distinctive dorsal ridges and large dewlaps, forming a very powerful appearance. Females are substantially smaller, and their dorsal ridges and dewlaps are less developed. Their dark brown coats are short and dense. There are dewlaps under the chin which extend between the front legs. They have shoulder humps, especially pronounced in adult males.
