A rare Steller sea lion was spotted lounging on the docks at Pier 39 in San Francisco's Fisherman's Wharf neighborhood. The large marine mammal, which can weigh up to 2,500 pounds, was photographed resting near a raft of California sea lions, a more common sight at the popular tourist destination.

Why it matters

Sightings of Steller sea lions in the San Francisco Bay Area are extremely rare, as their normal range is much farther north along the Pacific coast. This unexpected appearance has generated excitement among local marine life enthusiasts and raised questions about what may have drawn the massive creature so far south.

The details

The Steller sea lion was photographed on Monday afternoon by a visitor to Pier 39. The animal appeared to be resting peacefully alongside the more numerous California sea lions that frequently bask on the docks. Steller sea lions are the largest of the eared seals, growing up to 11 feet long and weighing as much as 2,500 pounds.
