A massive Steller sea lion nicknamed "Chonkers" has become a viral sensation at Pier 39 in San Francisco [1].
The animal's arrival highlights the public's fascination with rare wildlife sightings in urban areas and has turned a popular tourist spot into a temporary wildlife exhibit.
Chonkers is a Steller sea lion, known scientifically as Eumetopias jubatus [1]. The animal has drawn large crowds to the Fisherman's Wharf area because of its unusual size [2]. While typical male Steller sea lions average 1,200 pounds [4] and reach lengths of 10 feet [4], Chonkers is significantly larger.
Experts estimate the animal weighs approximately 2,000 pounds [4]. This weight makes the sea lion roughly three times the size of a typical California sea lion [5]. Some reports have described the animal as a "one-ton sea lion" [3].
Visitors have flocked to the pier in recent weeks to catch a glimpse of the creature [2]. The sea lion's presence has transformed the waterfront into a hub of social media activity, as tourists share videos of the animal's scale compared to other sea lions frequenting the docks.
Steller sea lions are distinct from the more common California sea lions often seen in the bay. Their massive bulk and different physical characteristics make them a novelty attraction in the city [1]. The animal has remained a focal point for visitors seeking a rare encounter with such a large marine mammal [2].
“Chonkers is approximately 2,000 pounds.”
The viral popularity of Chonkers underscores the impact of social media on wildlife tourism, where a single animal can drive significant foot traffic to a specific geographic location. It also provides a public opportunity to observe the physical differences between Steller and California sea lions in a natural, albeit urban, setting.
