Lions: In some areas where lions and rhinos co-exist, lions may occasionally prey on young or sick rhinos, especially if the rhino is already weakened or injured.
Hyenas: Hyenas are known to scavenge on rhino carcasses, and in rare instances, they may attack young or weakened rhinos.
Leopards: While leopards typically prey on smaller animals, they have been known to attack young rhinos on occasion.
Crocodiles: In areas where rhinos have access to water sources, crocodiles may pose a threat, particularly to calves.
Humans: The most significant threat to rhinos is not from predators but from humans. Poaching for their horns is the primary cause of rhino decline.
Other factors: Disease, habitat loss, and competition with other herbivores can also affect rhino populations.
It's important to remember that the relationship between rhinos and these animals is complex, and the frequency of predation is relatively low. The primary threats to rhinos are human-induced, such as poaching and habitat loss.
