There are two white African species of rhino, one is the Northern White Rhino and the other is the Southern White Rhino. Unlike other rhinos, White Rhinos have poor vision so they rely on hearing, smell and their sense of touch to detect predators and prey. Additionally, White Rhinoceros' also use natural echolocation for navigation. White Rhinoceros' natural habitat occupies a wide geographic range since they can survive in both mountainous and flatlands (even turning up in Kruger Park's blackthorn bush). They feed primarily on grasses; however, they will eat leaves if food is scarce or buds from trees when grasses aren't available.
