* Defense: The most prominent reason is for defense against predators. The horns are used as weapons to fight off lions, hyenas, and other threats. Their horns are incredibly strong and can inflict serious damage.
* Social Interactions: Horns are also used in social interactions within their herds. Males use them to establish dominance and compete for mates. They may also use their horns in territorial disputes.
* Foraging: While not their primary function, the horns can be used to push aside branches and vegetation while grazing.
The Structure of the Horn:
It's important to note that rhinoceros horns are not made of bone but rather of a keratinous material similar to human hair and nails. They grow continuously throughout the rhino's life.
Poaching:
Unfortunately, the horns of black rhinos have become a target of poaching for use in traditional medicine and other purposes. This has led to a dramatic decline in their population and a critical need for conservation efforts.
