Discover more about Sea Lions

The sea lions of Pier 39 have become an iconic symbol of San Francisco, drawing millions of visitors each year to witness their captivating behavior and listen to their distinctive barks. Their story began in the aftermath of the Loma Prieta earthquake in October 1989, when a small group of sea lions started to haul out on Pier 39's K-Dock. By January 1990, their numbers had exploded, with hundreds of the animals crowding onto the docks, much to the initial dismay of the marina's tenants. Faced with a growing colony of noisy, blubbery residents, the Pier 39 management sought advice from The Marine Mammal Center. The recommendation was to allow the sea lions to stay, recognizing the potential for a unique and engaging attraction. The decision proved to be a stroke of genius, as the sea lions quickly became a major draw, transforming Pier 39 into a must-see destination. The sea lions are California sea lions ( *Zalophus californianus*), known for their intelligence, playfulness, and loud vocalizations. Males can weigh up to 800 pounds and reach lengths of 7 feet, while females are smaller, typically weighing around 200 pounds. They are opportunistic feeders, preying on a variety of fish and squid found in the San Francisco Bay. The population of sea lions at Pier 39 fluctuates throughout the year, influenced by factors such as food availability and breeding cycles. The largest gatherings typically occur between late July and October, when hundreds of sea lions can be seen lounging on the docks. During the winter months, many of the animals migrate south to breeding grounds off the coast of Southern California, leading to a decrease in the pier's population. However, a core group of sea lions remains year-round, ensuring that visitors can always catch a glimpse of these fascinating creatures. One of the most remarkable aspects of the Pier 39 sea lion colony is their adaptability. They have learned to coexist with humans in a busy urban environment, becoming accustomed to the noise and activity of the pier. Despite their proximity to people, the sea lions remain wild animals and are protected by the Marine Mammal Protection Act. It is illegal to feed, harass, or otherwise disturb them. Visitors to Pier 39 can observe the sea lions from a variety of vantage points. The pier offers designated viewing areas with informative displays about the animals' biology, behavior, and conservation status. Knowledgeable docents from The Marine Mammal Center are often on hand to answer questions and provide insights into the lives of these marine mammals. The sea lions' antics are endlessly entertaining. They can be seen basking in the sun, often piled on top of each other in a seemingly chaotic heap. They engage in frequent squabbles, barking and jostling for prime dock space. They also display remarkable agility in the water, swimming, diving, and playing with each other. The Marine Mammal Center plays a crucial role in monitoring and protecting the Pier 39 sea lion colony. The center's staff and volunteers conduct regular surveys of the population, tracking their numbers, health, and behavior. They also respond to reports of sick or injured animals, providing medical care and rehabilitation when necessary. The sea lions of Pier 39 have not been without their challenges. In the past, they have faced threats from entanglement in marine debris, exposure to toxins, and competition for food resources. However, thanks to the efforts of conservation organizations, government agencies, and concerned citizens, the sea lion population has remained relatively stable in recent years.
