📖 1. Overview
The largest extant odd-toed ungulate, a heavily armored giant of the grasslands with broad lips suited for grazing.
🌐 Wikipedia Summary ExtractThe white rhinoceros, white rhino or square-lipped rhinoceros is the largest extant species of rhinoceros. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 17,464 individuals in the wild as of the end of 2023, and the much rarer northern white rhinoceros. The northern subspecies is critically endangered and on the brink of extinction; it has only two confirmed left as of 2018. Sudan, the world's last known male northern white rhinoceros, died in Kenya in March 2018. White rhinoceros can run up to 40 mph (64 km/h) for very short bursts. They can maintain speeds of around 30–31 mph (48–50 km/h) for a good amount of time, and they have good stamina.
