Another Steller sea lion has arrived at San Francisco’s Pier 39, claiming a spot on K-Dock, according to Pier 39 spokesperson Sue Muzzin. Pier officials confirmed the visiting pinniped is a separate animal likely visiting to feed on local schooling fish.
Pier 39 Staff Identify New Steller Sea Lion Visitor
The newly arrived Steller sea lion was spotted on K-Dock, prompting immediate comparisons to Chonkers, the Prius-sized male that dominated local headlines earlier in the year. According to Pier 39 spokesperson Sue Muzzin, the new arrival appears slightly smaller than the previous viral resident. Muzzin referred to the pinniped over the phone as probably being Chonkers’ buddy. Longtime harbormaster Sheila Chandor noted that Steller sea lion sightings have increased significantly this year compared to previous seasons. Officials attribute the surge in marine mammal activity directly to food availability, as the animals target dense schools of anchovies, herring, capelin, and salmon to feed.
Did you know? Steller sea lions are the largest of all eared seals, distinguished by their bear-like faces. They can grow up to 11 feet long and weigh as much as 2,500 pounds, making them roughly three times the size of standard California sea lions.
Comparing the Current Sighting to Chonkers’ Viral Stay
While California sea lions are a permanent fixture at Pier 39, Steller sea lion appearances remain infrequent, though not entirely uncommon, according to Giancarlo Rulli, a spokesperson for the Marine Mammal Center. Chonkers captured international attention in March when he hauled himself onto K-Dock and stayed for a two-month residency. His massive proportions drew crowds three rows deep and sparked a wave of social media mania, prompting the Marine Mammal Center to release a plushie that sold out almost instantly. By contrast, Pier 39 staff do not plan to assign a nickname to the current visitor, as operations expect the animal to depart within a few days. Even so, management hopes the impressive marine mammal will draw holiday weekend crowds to the waterfront.
