Main Difference – White vs Black Rhino
Rhinoceros or rhinos are among the largest and the most powerful terrestrial animal on Earth. White rhino and black rhino are the two living species native to the African continent. They are considered as Africa’s most endangered mammals due to extensive hunting for their horns, which are made up of keratin. The horns of rhinos are mainly used for ornamental and medicinal purposes. Both males and females possess a pair of horns, which is mainly used as an effective weapon. Other than humans, rhinos have no other natural enemies. They are herbivores and have very poor eyesight. Nevertheless, their sense of smell and hearing are very well developed. The difference between white and black rhino cannot be explained by their body colors. Both species have thick greyish-brown skin color. The most prominent physical difference is the shape of their mouth. White rhinos have a broad mouth with flat lips, which are used for grazing, whereas black rhinos have long, prehensile, pointed lips, which are used for browsing. This is the main difference between white and black rhino. More differences will be covered in this article.
