It is hard to guess what a Ribbon seal weights. But we have the answer:
An adult Ribbon seal (Phoca fasciata) on average weights 90 kg (198.42 lbs).
The Ribbon seal is from the family Phocidae (genus: Phoca). It is usually born with about 10.2 kg (22.49 lbs). They can live for up to 31 years. When reaching adult age, they grow up to 1.54 meter (5′ 1″). Usually, Ribbon seals have 1 babies per litter.
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 ribbon seal (Histriophoca fasciata) is a medium-sized pinniped from the true seal family (Phocidae). A seasonally ice-bound species, it is found in the Arctic and Subarctic regions of the North Pacific Ocean, notably in the Bering Sea and Sea of Okhotsk. It is distinguished by its striking coloration, with two wide white strips and two white circles against dark brown or black fur.It is the only living species in the genus Histriophoca, although a possible fossil species, H. alekseevi, has been described from the Miocene of Moldova.
