Steller Sea Lion

Eumetopias jubatus

Near Threatened

It could become threatened in the near future if current threats go unchecked.

Spotted something wrong?

The Steller sea lion is the largest of the eared seals: an adult male can weigh over a tonne. It breeds in dense colonies on rocky islets in the North Pacific and spends the rest of the year fishing for pollock, salmon, herring and squid. The western population, in Alaska, collapsed by more than 80% between the 1970s and the 1990s for reasons still debated, among them changes in prey abundance caused by industrial fishing and predation by killer whales.
