DK Adult (2005), Unverified reports of a body mass up to from Vietnam are considered dubious, since they far exceed other recorded weights for the species. Kouprey have tall, narrow bodies, with long legs and humped backs. They can be grey, dark brown or black. The horns of the female are lyre-shaped, with antelope-like upward spirals. The horns of the male are wide, and arch forwards and upward; they begin to fray at the tips at about three years of age. Both sexes have notched nostrils and long tails.

. Their preferred habitat is open forest and savannas often near thick monsoon forests. They are diurnal, eating in the open at night and under the forest cover during the day. They usually travel up to 15 km in a night. They live in herds of up to 20 and are usually led by a single female. These herds generally consist of cows and calves, but have bulls during the dry season. Older males form bachelor herds. Many herds are known to break up and rejoin as they travel and have been found to be mixed in with herds of banteng or wild buffalo.

Ongoing conservation efforts

Kouprey are legally protected in all range states and may be present in some protected areas. Prince Sihanouk designated it as the national animal of Cambodia in the 1960s, partly due to its mystique. On the 15th and 16th of January 1988, the

report lists the kouprey as critically endangered (possibly extinct). Large mammal surveys continue to take place in Cambodia, hoping to rediscover living kouprey. Other surveys have been taking place in the kouprey's historical range as recently as 2011. These surveys were done to determine the regions in their range with the highest probability of the kouprey's persistence. This is based on the habitat type and survey effort to date.

. However, the authors of this study rescinded their conclusion. Because a fossilized skull was found dating from the late Pleistocene or early Holocene epoch, they concluded the kouprey is not a hybrid.
