Core Event: Arrival and Extended Stay
In mid-March 2026 a 2,000-pound Steller sea lion nicknamed “Chonkers” was first seen lounging on the floating dock at San Francisco’s Pier 39. He has remained there for about a month, the longest continuous stay recorded in the past 15 years.
Species Background & Pier 39 Context
Steller sea lions are a northern-Pacific species that normally live on offshore rookeries such as the Farallon Islands. Adult males can weigh up to 2,500 lb and reach 11 ft; females up to 1,000 lb and 9 ft. California sea lions at Pier 39 rarely exceed 850 lb or 7 ft. Pier 39 has hosted sea-lion colonies since the 1989 Loma Prieta earthquake, supporting thousands during seasons.
Key Figures
Sheila Chandor, Laura Gill, Stephen Arsenault are primary officials.
Data & Statistics
Weight estimates range 1,500–2,000 lb (? 680–907 kg). Length is about two to three times that of typical pier sea lions. Daily pier counts vary from dozens to several hundred. Reported origin distances are roughly 30 mi from the Farallon Islands or from Washington/Oregon coast.
Community Impact
Chonkers’ size and rarity have drawn visitors nationwide, increasing foot traffic at the tourist hub. Harbor officials note his presence signals abundant anchovies, sardines, and rockfish. Residents report spontaneous gatherings of families and strangers, describing the sight as a “happy, fun story.”
Official Statements & Responses
Chandor said Chonkers’ stay is “great for the health of the bay” and encourages community bonding. Gill emphasized the likely offshore origin and noted shallow bay waters provide a predator-free foraging zone rich in prey. Arsenault reported the sea lion typically appears around 7:30 a.m., stays on the dock until about 10 a.m., then returns to the water. Each official highlighted a different aspect of Chonkers’ presence, from ecological health to foraging conditions and daily behavior.
Verbatim Quotes

Criticism & Opposition
No environmental, safety, or regulatory concerns have been reported.
Conflicting Reports & Gaps
Sources differ on Chonkers’ exact weight (1,500–2,000 lb versus a fixed 2,000 lb) and on his probable origin (Farallon Islands versus Washington/Oregon coast). The animal’s sex has not been confirmed in any report.
What’s Next
The Marine Mammal Center will continue to monitor Chonkers and assess whether additional Steller sea lions appear at Pier 39. Harbor officials plan to maintain the floating platforms to support both resident California sea lions and occasional visitors like Chonkers. Future sightings will be documented by the center.
