No, no, no! the horned antelope is indeed a bovine.
This is followed by experts from the Shanghai Zoo to understand cattle in the biological sense.
The bovine family, belonging to the order Even-ungulate-ruminant suborder-bovine, is the most successful and progressive family of ungulates, with a total of 50 genera and 144 species. Bovines are highly adaptable, and almost half of the ungulates are bovines.
Wildebeest: I'm sorry guys, I'm really not a horse.
Bovines have a distinctive feature: both males and females have horns (unlike deer, only males have horns).

At the same time, due to long-term herbivorous reasons, the canine teeth and incisors of bovines have been seriously degraded, and in order to better digest food, bovines have evolved a very perfect rumination function.
After the cattle eat, the food flows sequentially through these 4 stomachs: rumen, hive stomach, heavy flap stomach and wrinkle stomach.
Rock sheep
The English name is blue sheep
Protection level: National grade II protected wildlife, iUCN no danger (lc)
Rock sheep, mainly distributed in the Qinghai-Tibet Plateau and surrounding mountains, are an important food source for predators such as snow leopards, wolves, and brown bears. As a link in the food chain in nature, the distribution and survival status of rock sheep populations will greatly affect the survival of other rare wild animals.
However, the rock sheep has also practiced the kung fu of "flying cornice walking wall" to avoid the hunting of natural enemies, and can use the limited foothold on the 70-degree slope wall to balance the body and walk freely, and is a "climbing expert". As the only part in contact with the rock wall, the hooves of rock sheep may play a crucial role in their excellent climbing ability. Microscopic studies have found that the surface of the hoof has a straight and curled microsheet-like form, and the cross-section presents four layers, and each layer has a unique structure. These factors help mitigate high impact strength and increase contact stability.
The design of the rock sheep exhibition area of Shanghai Zoo simulates the wild habitat environment of the rock sheep, and according to some special biological habits of the rock sheep, a number of rocks, rockeries, dead trees, etc. can be built for jumping, dodging and inhabiting, not only so that the rock sheep can stand on the high ground of the rock and look around, but also the color of the rock rock is almost exactly the same as the color of the rock wool, simulating the wild habitat environment, so that in the environment without natural enemies, the rock sheep can also obtain a hidden natural effect.
