It is hard to guess what a Mariana fruit bat weights. But we have the answer:
An adult Mariana fruit bat (Pteropus mariannus) on average weights 458 grams (1.01 lbs).
The Mariana fruit bat is from the family Pteropodidae (genus: Pteropus). When reaching adult age, they grow up to 21.7 cm (0′ 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 Mariana fruit bat (Pteropus mariannus), also known as the Mariana flying fox, and the fanihi in Chamorro, is a megabat found only in the Mariana Islands and Ulithi (an atoll in the Caroline Islands). Habitat loss has driven it to endangered status, and it is listed as threatened by the US Fish and Wildlife Service. Poachers and food hunters, other animals, and natural causes have led to the decline.
