156 male Tibetan antelopes in total in Mayi Snow Mountain玛依雪山 in Qiangtang Nature Reserve羌塘自然保护区, the ones with big body and long horns were adult male Tibetan antelopes, while the ones with smaller body and short horns were sub-adult male Tibetan antelopes that were born last year. They stood in the water, shaking their bodies and tails. This bathing behavior of the Tibetan antelope in the water actually cools down and removes parasites. In summer, there is a big temperature difference between day and night on the plateau, although the thick fur of the Tibetan antelope can keep the cold away at night, but at noon, it will be very hot, so the Tibetan antelope will soak in the water to cool down; in addition, there are more mosquitoes and parasites in summer, so the Tibetan antelope soak in the water can clean some parasites on the body surface.
