It is hard to guess what a Brown howler weights. But we have the answer:
An adult Brown howler (Alouatta fusca) on average weights 5.19 kg (11.44 lbs).
The Brown howler is from the family Cebidae (genus: Alouatta). When reaching adult age, they grow up to 51.5 cm (1′ 9″).
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 brown howler (Alouatta guariba), also known as brown howler monkey, is a species of howler monkey, a type of New World monkey that lives in forests in southeastern Brazil and far northeastern Argentina (Misiones). It lives in groups of two to 11 individuals. Despite the name “brown howler”, it is notably variable in colour, with some individuals appearing largely reddish-orange or black.The two subspecies are:Northern brown howler (A. g. guariba), listed as critically endangeredSouthern brown howler (A. g. clamitans)
