A massive Steller sea lion nicknamed “Chonkers” has arrived at Pier 39 in San Francisco, drawing large crowds of residents and tourists [1].
The animal's presence is significant because its size makes it a novelty compared to the smaller California sea lions that typically frequent the Fisherman's Wharf area [3].
Chonkers weighs approximately 2,000 pounds [4]. This immense size distinguishes the animal from the local population, leading to a surge of onlookers gathering at the wharf to observe the sea lion [2].
The arrival of Chonkers is not an isolated event for the region. At least two Steller sea lions have been spotted in San Francisco during the month of April 2024 [1].
Steller sea lions are considerably larger than the California sea lions usually seen at the pier. The presence of such a large animal in a high-traffic tourist zone has created a spectacle for visitors in the U.S. city [2, 3].
Local observers said the sea lion has effectively stolen the attention of the wharf, as crowds gather specifically to see the animal [3]. While the animal remains a point of curiosity, its presence highlights the occasional movement of larger Steller sea lion species into areas dominated by their smaller cousins [1].
“Chonkers weighs approximately 2,000 pounds.”
The appearance of Chonkers and other Steller sea lions in San Francisco illustrates the intersection of urban tourism and wildlife migration. While the California sea lion is a permanent fixture of Pier 39, the arrival of the much larger Steller species provides a rare opportunity for the public to observe the size difference between these pinnipeds in a shared habitat.
