Yellow-backed duiker
These forest dwelling antelope feed selectively on plants or plant parts such as shoots, roots, leaves, and buds, but their diet is mainly made up of fruits. The yellow-backed duiker is more efficient at digesting poor quality food than most other duiker species. This allows them to eat large, low quality fruits. Their diet makes them very hard to keep in captivity as most domesticated fruits are not well suited to their low fiber requirements. They are considered concentrate selectors, meaning they eat "diets relatively low in fiber, have a well developed ability to forage selectively, a rumen bypass, a rapid passage and high fermentation rate for starch, and they frequently encounter toxins."
Snow leopard

It can kill animals two to four times its own weight, such as Himalayan blue sheep, Himalayan tahr, markhor, argali, and juvenile horses and camels. It prefers prey ranging in weight from , but also hunts smaller mammals such as marmot, pika and vole species.
