Animal Weight

How much does a Steller sea lion weight?

It is hard to guess what a Steller sea lion weights. But we have the answer:

An adult Steller sea lion (Eumetopias jubatus) on average weights 383.23 kg (844.88 lbs).

The Steller sea lion is from the family Otariidae (genus: Eumetopias). It is usually born with about 18.28 kg (40.29 lbs). They can live for up to 30 years. When reaching adult age, they grow up to 2.7 meter (8′ 11″). Usually, Steller 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 Steller sea lion (Eumetopias jubatus), also known as the Steller’s sea lion and “northern sea lion”, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus Eumetopias and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers over an extensive portion of their northern range in Alaska.
