It is hard to guess what a Sumatran orangutan weights. But we have the answer:
An adult Sumatran orangutan (Pongo abelii) on average weights 39.7 kg (87.51 lbs).
The Sumatran orangutan is from the family Hominidae (genus: Pongo). When reaching adult age, they grow up to 4.5 cm (0′ 2″).
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 Sumatran orangutan (Pongo abelii) is one of the three species of orangutans. Found only in the north of the Indonesian island of Sumatra, it is rarer than the Bornean orangutan but more common than the recently identified Tapanuli orangutan, also of Sumatra. Its common name is based on two separate local words, “orang” (“people” or “person”) and “hutan” (“forest”), derived from the official language of Malaysia, Malay, and translates as ‘person of the forest’.
