It is hard to guess what a South American sea lion weights. But we have the answer:
An adult South American sea lion (Otaria flavescens) on average weights 193.67 kg (426.97 lbs).
The South American sea lion is from the family Otariidae (genus: Otaria). It is usually born with about 12.82 kg (28.26 lbs). They can live for up to 24.75 years. When reaching adult age, they grow up to 2.11 meter (7′ 0″). Usually, South American sea lions 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 South American sea lion (Otaria flavescens, formerly Otaria byronia), also called the Southern Sea Lion and the Patagonian sea lion, is a sea lion found on the Ecuadorian, Peruvian, Chilean, Falkland Islands, Argentinean, Uruguayan, and Southern Brazilian coasts. It is the only member of the genus Otaria. Its scientific name was subject to controversy, with some taxonomists referring to it as Otaria flavescens and others referring to it as Otaria byronia. The former eventually won out, although that may still be overturned. Locally, it is known by several names, most commonly lobo marino (es)/lobo marinho (pt) (sea wolf) and león marino (es)/leão marinho (pt) (sea lion) and the hair seal.
