How old does a Waterbuck get? (age expectancy)

What is the maximal age a Waterbuck reaches?

An adult Waterbuck (Kobus ellipsiprymnus) usually gets as old as 19.92 years.

Waterbucks are around 270 days in the womb of their mother. When born, they weight 12 kg (26.46 lbs) and measure 8.5 cm (0′ 4″). As a member of the Bovidae family (genus: Kobus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 10.2 cm (0′ 5″).

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.

A Waterbuck gets as old as 19.92 years

The waterbuck (Kobus ellipsiprymnus) is a large antelope found widely in sub-Saharan Africa. It is placed in the genus Kobus of the family Bovidae. It was first described by Irish naturalist William Ogilby in 1833. The thirteen subspecies are grouped under two varieties: the common or Ellipsiprymnus waterbuck and the Defassa waterbuck. The head-and-body length is typically between 177–235 cm (70–93 in) and the average height is between 120 and 136 cm (47 and 54 in). A sexually dimorphic antelope, males are taller as well as heavier than females. Males reach approximately 127 cm (50 in) at the shoulder, while females reach 119 cm (47 in). Males typically weigh 198–262 kg (437–578 lb) and females 161–214 kg (355–472 lb). The coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward and are 55–99 cm (22–39 in) long.Waterbuck are rather sedentary in nature. A gregarious animal, the waterbuck may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of five years, but are most dominant from the age of six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts for seven to eight months, followed by the birth of a single calf.Waterbuck inhabit scrub and savanna areas along rivers, lakes and valleys. Due to their requirement for grasslands as well as water, the waterbuck have a sparse ecotone distribution. The IUCN lists the waterbuck as being of Least Concern. More specifically, the common waterbuck is listed as of Least Concern while the defassa waterbuck is Near Threatened. The population trend for both the common and defassa waterbuck is downwards, especially that of the latter, with large populations being eliminated from certain habitats because of poaching and human disturbance.
