What is the maximal age a White rhinoceros reaches?
An adult White rhinoceros (Ceratotherium simum) usually gets as old as 50 years.
White rhinoceross are around 534 days in the womb of their mother. When born, they weight 48.5 kg (106.92 lbs) and measure 20 cm (0′ 8″). As a member of the Rhinocerotidae family (genus: Ceratotherium), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 2.59 meter (8′ 6″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The white rhinoceros or square-lipped rhinoceros (Ceratotherium simum) 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 19,682–21,077 wild-living animals in the year 2015, and the much rarer northern white rhinoceros. The northern subspecies has very few remaining individuals, with only two confirmed left in 2018 (two females; Fatu, 18 and Najin, 29), both in captivity. Sudan, the world’s last known male northern white rhinoceros, died in Kenya on 19 March 2018.
