Except for females and their offspring, black rhinos are solitary. Females reproduce only every two and a half to five years. Their single calf does not live on its own until it is about three years old.
Black rhinos feed at night and during the gloaming hours of dawn and dusk. Under the hot African sun, they take cover by lying in the shade. Rhinos are also wallowers. They often find a suitable water hole and roll in its mud, coating their skin with a natural bug repellent and sun block.
Rhinos have sharp hearing and a keen sense of smell. They may find one another by following the trail of scent each enormous animal leaves behind it on the landscape.
Black rhinos boast two horns, the foremost more prominent than the other. Rhino horns grow as much as three inches (eight centimeters) a year, and have been known to grow up to five feet (one and a half meters) long. Females use their horns to protect their young, while males use them to battle attackers.
