A 10-foot-long Steller sea lion arrived at Pier 39 this week, securing a space for itself among the local colony. The visitor has replaced the previous Steller sea lion known as Chonkers, who has since departed the harbor.

Why it matters

The presence of a Steller sea lion at the marina is notable as they are significantly less common in the area than the resident California sea lions. The animal is likely drawn to the harbor to take advantage of the local schools of sardines.

The new arrival measures 10 feet in length and displays visible scarring across its body. Staff at the pier have monitored the location for 41 years.

This scientific institution employs the staff members who have observed the wildlife at Pier 39 for over four decades.

The details

The Steller sea lion established its presence on the crowded K-Dock, likely following the resident California sea lions into the harbor. It remains in the area to feed on the local sardine population.

Culture Shift

This sighting highlights the unique biodiversity shifts in urban marine environments like San Francisco. Such visits mark a deviation from the historical demographic distribution of pinnipeds at Pier 39.

Residents and tourists visiting Pier 39 can view the new arrival as it rests on the K-Dock. Observers are reminded to maintain a respectful distance to avoid disturbing the animal during its stay.

The takeaway

Wildlife enthusiasts should take note that Steller sea lions are distinct from the more common California sea lion species often found at the docks. Observing these animals requires patience and a commitment to keeping the harbor environment undisturbed.
