How much does a Rio Mayo titi weight?

It is hard to guess what a Rio Mayo titi weights. But we have the answer:

An adult Rio Mayo titi (Callicebus oenanthe) on average weights 992 grams (2.19 lbs).

The Rio Mayo titi is from the family Cebidae (genus: Callicebus). When reaching adult age, they grow up to 35.8 cm (1′ 3″). Usually, Rio Mayo titis have 1 babies per litter.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The Rio Mayo titi (Plecturocebus oenanthe) is a species of titi, a type of New World monkey, endemic to Peru. The Rio Mayo titi, was thought previously to have a small range of origin in the Alto Mayo valley, but research has proven that the range extends southward and reaches the Huayamba River, as well as Bajo Mayo. It had been classified as vulnerable but due to major habitat loss and restricted living space, it is now classified as Critically Endangered. In October 2012, it was included in The World’s 25 Most Endangered Primates list. An increase in deforestation is leading to the decrease in available living space for this titi monkey, forcing it to live in sympatry with another species of Callicebus. Yet in some areas, such drastic deforestation has resulted in extremely high population density. The Rio Mayo titi is better adapted to moderately populated areas, thus overpopulation negatively impacts the species. The forests the Rio Mayo titi lives in are being destroyed for agricultural purposes, leaving little forest for the monkeys. They were only seen a few times and featured in museums until 2003 when more research was done on them. In order for this species to survive, their forests need to be protected to avoid overpopulation. Different conservation groups are working to help P. oenanthe survive. Neotropical Primate Conservation, Proyecto Mono Tocón and Amazónicos para la Amazonia are working in the more southern areas to protect the monkey.The Rio Mayo titi is a fairly inconspicuous creature, making observation and research difficult to obtain. Therefore, the traditional use of transect observation to monitor the monkey’s population, is less effective. Instead, other methods of calculating the titi monkey’s density in certain areas have been taken, such as research into the species-specific calls endemic to a certain area.
