Species and Distribution
Species of Rhino
There are five species of rhinoceros:
- African rhinos: Black rhino (Diceros bicornis) and White rhino (Ceratotherium simum)
- Asian rhinos: Indian or Greater one-horned rhino (Rhinoceros unicornis), Javan rhino (Rhinoceros sondaicus), and Sumatran rhino (Dicerorhinus sumatrensis)
White rhinos are the most abundant, with around 20,000 individuals, mostly in southern Africa. Black rhinos number around 5,500, with the majority in southern and eastern Africa. The three Asian rhino species are all critically endangered, with only a few hundred individuals each.
Physical Characteristics
- Rhinos are large, herbivorous mammals known for their distinctive horns.
- Their horn is made of keratin, the same material as human fingernails. It continues to grow throughout the rhino’s life.
- White rhinos and Indian rhinos have one horn, while black, Javan and Sumatran rhinos have two horns.
- The white rhino is the largest, weighing up to 2,500 kg (5,500 lbs). The Sumatran rhino is the smallest, weighing 500-800 kg (1,100-1,800 lbs).
- Rhinos have thick, grey skin with little hair. Their eyes are small, but their other senses like smell are very acute.
Behavior and Ecology
- Rhinos are herbivores, feeding on grasses, leaves, shoots and fruits.
- They wallow in mud to regulate their body temperature and protect their skin from insects and sunburn.
- Rhinos are generally solitary or live in small groups. White rhinos are more social, living in larger herds.
- Reproduction is slow, with a gestation period of 15-18 months. Females give birth to one calf every 2-4 years.
- Rhinos have few natural predators as adults, but calves may be vulnerable to lions, tigers, crocodiles and hyenas.
Conservation Status
- Rhino populations declined dramatically in the 20th century due to poaching for their horns.
- The Javan and Sumatran rhinos are critically endangered, with fewer than 80 individuals each.
- Conservation efforts have helped increase numbers of Indian and southern white rhinos in recent decades.
- However, poaching remains a major threat, with 1,000 rhinos killed annually in Africa alone.
- Protecting rhinos and their habitats is crucial to ensure their survival for future generations.
In summary, rhinos are iconic megafauna facing serious threats to their existence. Continued conservation efforts are essential to prevent further declines and extinctions of these remarkable animals.
