Viral Sea Lion
A male Steller sea lion, dubbed “Chonkers,” began lounging on San Francisco’s Pier 39 in March 2026. Weighing about 2,000 pounds and up to 11 feet long, he dwarfs the resident California sea lions that average 850 pounds. Instagram clips of him sprawled on the dock earned thousands of likes and drew tourists seeking a glimpse, turning him into an internet sensation.
Background
Steller sea lions are rare at Pier 39, typically inhabiting waters from Alaska to Oregon. The eastern stock, likely Chonkers’, was delisted from the U.S. Endangered Species List in 2013 after recovery, while the western stock remains endangered. In northern California, breeding colonies are thought to exist near the Farallon Islands, about 30 miles offshore.

Data
Estimated weight 1,500–2,500 lb; length up to 11 ft. MMC has rescued >27,000 marine mammals and educates >50,000 people annually. Each plush sells for $39.95, with proceeds funding rescue and rehabilitation.
Official Response
The MMC called the plush a “huggable, squishable” tribute and emphasized that “every purchase helps give marine mammals in need a second chance.” Programs Manager Laura Gill said Chonkers appears healthy despite his size. UC Santa Cruz professor Daniel Costa suggested the sea lion may have moved to the Farallon Islands to establish territory before breeding, noting his absence could be brief.
Critique & Gaps
Some observers caution that a prolonged stay by a large marine mammal could affect local dynamics, though experts view Chonkers’ presence as natural, albeit rare. Sources differ on his weight—estimates range from 1,500 lb to 2,500 lb—and his location remains unverified; Costa cites the Farallon Islands, but no sighting confirms this. Plush sales figures have not been disclosed.
