Crowds gathered at Pier 39 in San Francisco, California, on Thursday, April 30, 2026 [2], to see a large Steller sea lion nicknamed “Chonkers” [1].
The event drew significant attention because Steller sea lions are a rare sight at the pier. The location is typically occupied by smaller California sea lions, making the presence of a larger species a novelty for tourists and locals alike [1].
Observers noted the animal's unusual size compared to the resident population. According to reports, at least two Steller sea lions have been spotted in the area this month [1]. The arrival of these animals has turned the waterfront into a temporary attraction, drawing large groups of visitors to the docks.
Claire Cook said, "Steller sea lion appearances were unusual" [3].
While the California sea lions are a permanent fixture of the San Francisco waterfront, the intermittent appearance of the Steller variety creates a distinct contrast in scale. The animal known as Chonkers became the center of attention for the crowds gathered on Thursday [2].
Local wildlife sightings often fluctuate based on seasonal migrations and food availability. The presence of multiple Steller sea lions in a single month suggests a temporary shift in regional patterns [1]. Visitors continued to document the animal as it rested among the smaller sea lions at the pier [1].

The appearance of Steller sea lions at Pier 39 is a biological anomaly for the site, as the area is dominated by the smaller California sea lion species. The sighting of at least two such animals within one month indicates a rare overlap in habitat or a temporary migratory shift that attracts public interest and disrupts the typical wildlife composition of the San Francisco waterfront.
