Our next rhinoceros fact talks about the animal’s name origin.

The term "rhinoceros" originates from two Greek words: "rhinos," meaning "nose," and "keras," meaning "horn." These animals have a prominent horn on their nose, which gives them their name. However, these horns aren't just decorative; they serve as the rhino's first line of defense. Black, white, and Sumatran rhinoceroses have two horns, with the larger one being called the anterior horn, and can grow up to 59 inches.

The posterior horn is shorter and can grow up to 22 inches. Besides self-defense, rhino horns are also for practical purposes such as digging for water and breaking branches2. Indian and Javan rhinos use their single horns in the same way.
