It is hard to guess what a Red-handed howler weights. But we have the answer:
An adult Red-handed howler (Alouatta belzebul) on average weights 6.17 kg (13.6 lbs).
The Red-handed howler is from the family Cebidae (genus: Alouatta). When reaching adult age, they grow up to 55.1 cm (1′ 10″).
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 red-handed howler (Alouatta belzebul) is a vulnerable species of howler monkey, a type of New World monkey. It is endemic to Brazil, found in the southeastern Amazon and disjunctly in the Atlantic Forest between Rio Grande do Norte and Sergipe.
