Environment COP26 nears conclusion with mixed signals and frustration. Speaking of toes, rhinos do have one weak spot. Rhinos typically put most of their weight on their toenails when they walk to avoid wearing out their sensitive feet.
This is easy to do in the wild, where marshes and mushy wetlands abound, but when they're brought to zoos, their toenails tend to wear down on hard surfaces like concrete and asphalt.
This can lead to swollen, sore, and cracked feet, making them more susceptible to infection. To tackle this issue, one zoo glued modified horseshoes onto a rhino's toes, which you can read about in the book The Rhino With Glue-On Shoes. But not because they're depressed. For a rhino, a nice mud bath is like a day at the spa. It not only helps the animals cool down in hot weather, but it's also great for their skin, helping to ward off pesky insects.
Although the animals have a pretty thick dermis, they're surprisingly vulnerable when it comes to bug bites and sunburn. Rhino horns are made up of nothing but keratin, but that doesn't stop poachers from killing thousands of the animals each year and selling their horns on the black market.
The horns are fashioned into jewelry and figurines, and in some parts of Asia they're believed to hold healing properties they don't. Just a century ago, there were more than half a million rhinos around the world.
Now, around 30, survive in the wild, largely due to poaching. The white rhino is the larger African species, weighing 3, between and 7, pounds and standing at a height between 5 and 6 feet. Javan rhinos are 4. The greater one-horned rhino is the largest of the rhino species, with height ranging from 5. The rhinoceros gets its name from one of its most notable features: its horns. The two African species the black rhino and the white rhino and the Sumatran rhino have two horns, while the Javan rhino and one-horned rhino have one horn.
Thus, it can be easily scarred. To protect themselves against sunburn and insect bites, rhinos soak in mud or roll in dust. The Sumatran rhinos are the smallest of the living rhinos. They are covered with long hair and are more closely related to the extinct woolly rhinos than any of the other rhino species alive today. The greater one-horned rhino is identified by a single black horn, which is about 8 to 25 inches long.
They have a grey-brown hide with skin folds, which gives them an armor-plated appearance. The Javan rhino is very similar in appearance to the closely-related one-horned rhino, but the Javan rhino has a much smaller head and less apparent skin folds.
Javan rhinos are a dusky grey color and have a single horn of up to about 10 inches. Both species of African rhinos, black and white rhinos, are the same color. Of the two African species, black rhinos are the smaller species.
The most notable difference between white and black rhinos is their hooked upper lip. White rhinos are known for their square lip, which distinguishes them from the black rhino. Black rhinos are browsers rather than grazers, and their pointed lip helps them feed on leaves from bushes and trees. Black rhinos have two horns, and occasionally a third, small posterior horn.
All five species of rhinos are herbivores, eating mainly vegetation. They spend most of their time browsing and grazing through their natural habitat in search of plants and grasses to eat. The specific types of food that each of the species eats depend upon their habitat and location. Rhinos are one of the few remaining megaherbivores, which are plant-eaters that weigh more than 2, pounds. Their habitat depends on the species.
Meanwhile, the white rhino can be found in African grasslands. While rhinos once roamed great portions of Africa and Asia, their range has decreased dramatically in recent years. Their location depends on species. For example, the Sumatran rhino can be found on the Indonesian islands of Sumatra and Borneo.
