What is the maximal age a Black-headed spider monkey reaches?
An adult Black-headed spider monkey (Ateles fusciceps) usually gets as old as 24 years.
Black-headed spider monkeys are around 224 days in the womb of their mother. When born, they weight 500 grams (1.1 lbs) and measure 4 cm (0′ 2″). As a member of the Cebidae family (genus: Ateles), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 48.9 cm (1′ 8″).
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 black-headed spider monkey (Ateles fusciceps) is a species of spider monkey, a type of New World monkey, from Central and South America. It is found in Colombia, Ecuador, and Panama. Although primatologists such as Colin Groves (1989) follow Kellogg and Goldman (1944) in treating A. fusciceps as a separate species, other authors, including Froelich (1991), Collins and Dubach (2001) and Nieves (2005) treat it as a subspecies of Geoffroy’s spider monkey.The two subspecies are:Ateles fusciceps fusciceps – northwestern Ecuador.Ateles fusciceps rufiventris – southwest Colombia to eastern Panama.A. f. fusciceps lives in tropical and subtropical humid forests between 100 and 1,700 metres (330 and 5,580 ft) above sea level. It lives in population densities of 1.2 monkeys per square kilometer. A. f. rufiventris lives in dry forests, humid forests and cloud forests, and can live up to 2,000 to 2,500 metres (6,600 to 8,200 ft) above sea level.A. f. fusciceps has a black or brown body and a brown head. A. f. rufiventris is entirely black with some white on its chin. The black-headed spider monkey is one of the larger New World monkeys. The head and body length, excluding tail, typically ranges between 39.3 and 53.8 cm (15.5 and 21.2 in). The prehensile tail is between 71.0 and 85.5 cm (28.0 and 33.7 in). On average, males weigh 8.89 kilograms (19.6 lb) and females weigh 8.8 kilograms (19 lb). The brain weighs 114.7 g (4.05 oz).The black-headed spider monkey is arboreal and diurnal. It moves by climbing and brachiation. When mating, females may consort with a male for up to three days, or else mate with several males. Mating occurs with the male and female face to face, and can last for five to 10 minutes. The gestation period is between 226 and 232 days. The infant rides on its mother’s back for 16 weeks, and is weaned at 20 months. Females attain sexual maturity at 51 months; males at 56 months. Females give birth every three years.The black-headed spider monkey is considered to be critically endangered by the International Union for Conservation of Nature (IUCN) due to an estimated population loss of more than 80% over 45 years, from hunting and human encroachment on its range of habitation.Captive black-headed spider monkeys have been known to live more than 24 years.
