It is hard to guess what a Bolivian red howler weights. But we have the answer:
An adult Bolivian red howler (Alouatta sara) on average weights 6.61 kg (14.57 lbs).
The Bolivian red howler is from the family Cebidae (genus: Alouatta). When reaching adult age, they grow up to 56.7 cm (1′ 11″).
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 Bolivian red howler (Alouatta sara) is a species of howler monkey, a type of New World monkey, endemic to Bolivia. It can be found in rain forests, including riverine and seasonally flooded forests.
