What is causing the decrease of rhinoceros population?
Rhinoceros, often abbreviated as rhino, is a group of five surviving species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to Southern Asia.
Rhino species size comparison: Indian Rhino, over 1.8m, White Rhino, 1.8m, Black Rhino , over 1.5m, Javan Rhino, 1.5m and Sumatran Rhino, 1.4m
The Rhinos belong to the few present mega-fauna that still alive today. All species can weight more than a ton, and the White Rhino considered the second largest land mammal, can weigh up to 2,700 kg. Rhinos are herbivores; there are browsers and grazers. They have a small brain, with 1 or 2 horns, and a thick skin made of collagen with armor like structure. Different from other mammals, African Rhino species don’t have front teeth and use their lips to tear off grass or leaves while their molar teeth grind food. Leonardo Suarez

There are five species of rhinos: the White and the Black rhino from Africa, the Sumatran, the Javan and the Indian rhino from Southern Asia. Three of these five rhino species are classified by the International Union for Conservation of Nature (IUCN) as Critically Endangered — the Black Rhino, the Javan Rhino and the Sumatran Rhino, which means they are in the highest risk of extinction. The Indian or Greater One-Horned Rhino is classified as vulnerable, which means that are close to become endangered unless the situation threatening survival and reproduction improve and the White Rhino, near threatened that means they may be considered threatened with extinction in the near future. Critically endangered is the highest IUCN wild animal risk category and is connected to species facing an extremely high risk of extinction in the wild. The term threatened species
