Indonesia's environment minister shared a video of a rare Javan rhinoceros taking a mud bath in Ujung Kulon National Park.
It's believed there are just 72 of the animal left in the world.
The minister who shared the video, Siti Nurbaya Bakar, wrote that the rhinoceros had been identified as a 7-year-old male.
Listed as "critically endangered" on the International Union for Conservation of Nature's (IUCN) red list, the Javan rhinoceros is found only in the Ujung Kulon National Park. Forest rangers have been guarding the national park to prevent poachers from killing rhinos and removing their horns, which can fetch huge sums of money on the black market.
Siti also explained that rhinoceros take mud baths to protect their skin from sunburn, insect bites and other parasites as well as to maintain their skin's moisture. Mud baths also help rhinoceros cool down and fulfill their mineral needs. Rhinoceros could take mud baths twice a day, with each session taking up to three hours, Siti added.
