What is the maximal age a Jentink’s duiker reaches?
An adult Jentink’s duiker (Cephalophus jentinki) usually gets as old as 17.5 years.
When born, they weight 4.59 kg (10.11 lbs) and measure 20 cm (0′ 8″). As a member of the Bovidae family (genus: Cephalophus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 1.35 meter (4′ 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.
Jentink’s duiker (Cephalophus jentinki), also known as gidi-gidi in Krio and kaikulowulei in Mende, is a forest-dwelling duiker found in the southern parts of Liberia, southwestern Côte d’Ivoire, and scattered enclaves in Sierra Leone. It is named in honor of Fredericus Anna Jentink.Jentink’s duikers stand around 80 cm (31 in) tall at the shoulder and weigh about 70 kg (150 lb), making them the largest species of the duikers. They are gray from the shoulders back and dark black from the shoulders forward. A white band goes over the shoulders, between the two colours and joining the white undersides. Jentink’s duikers have long, thin horns, which curl back a little at the ends, and reach between 14 and 21 cm (5.5 and 8.3 in).Jentink’s duikers live mainly in very thick rainforest, where they eat fruit, flowers, and leaves which have fallen from the canopy, as well as stems of seedlings, roots, and, to the annoyance of local farmers, palm nuts, mangos, and cocoa pods. They are nocturnal and shelter during the day in dense thickets, or buttress roots, apparently in pairs. Jentink’s duikers are reported to be territorial animals, and when frightened, will run very quickly, but wear themselves out easily.The species was first recognized as a new species in 1884, though it was not described until 1892. The species then vanished until a skull was found in Liberia in 1948. Sightings have occurred in its habitat since the 1960s. In 1971, the species was successfully bred in the Gladys Porter Zoo.Recent population numbers are not available. In 1999 it was estimated that around 3,500 Jentink’s duikers remained in the wild, but the following year others suggested less than 2,000 were likely to remain. They are threatened primarily by habitat destruction and commercial bushmeat hunters.
