It is hard to guess what a Northern fur seal weights. But we have the answer:

An adult Northern fur seal (Callorhinus ursinus) on average weights 55.58 kg (122.54 lbs).

The Northern fur seal is from the family Otariidae (genus: Callorhinus). It is usually born with about 5.35 kg (11.8 lbs). They can live for up to 35 years. When reaching adult age, they grow up to 1.74 meter (5′ 9″). Usually, Northern fur seals have 1 babies per litter.
