CALIFORNIA SEA LIONS AT PIER 39

A few California sea lions began “hauling out” on PIER 39’s K-Dock shortly after the Loma Prieta earthquake hit San Francisco in October 1989. By January 1990, the boisterous barking pinnipeds started to arrive in droves and completely took over K-Dock, much to the exasperation of PIER 39’s Marina tenants.
The Marina Staff turned to The Marine Mammal Center, an organization devoted to the rescue and rehabilitation of marine mammals, for advice about their new slippery tenants. After much debate and research, the experts from The Marine Mammal Center recommended that the sea lions stay in their newfound home.

FUN FACTS ABOUT SEA LIONS
California sea lions are known for their intelligence, playfulness and noisy barking.

Although they usually avoid humans, sea lions may bite if provoked.

Male sea lions reach 850 lbs (390kg) and 7 ft (2. 1m) in length, while females can reach 220 lbs (110kg) and up to 6 ft (1. 8m) in length.

You can distinguish males from females: males develop a bump or “crest” on their heads at four or five years of age. A majority of the sea lions at PIER 39 are male.

Sea lions have external ear flaps—seals do not.

Sea lions in the wild may live up to 25 years.

Sea lions migrate to areas across the Pacific Coast, from Vancouver to the southern tip of Baja. Most pups are born on the Channel Islands, located off Southern California, in June.

California sea lions are protected by the Marine Mammal Protection Act. It is unlawful for unauthorized persons to feed, handle or harass them.

One of the biggest dangers to sea lions today is becoming entangled in plastic pollution.


Sea lions are pinnipeds characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short and thick hair, and a big chest and belly. Together with the fur seals, they make up the family Otariidae, eared seals. The sea lions have six extant and one extinct species (the Japanese sea lion) in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. They have an average lifespan of 20–30 years. A male California sea lion weighs on average about 300 kg (660 lb) and is about 2.4 m (8 ft) long, while the female sea lion weighs 100 kg (220 lb) and is 1.8 m (6 ft) long. The largest sea lions are Steller's sea lions, which can weigh 1,000 kg (2,200 lb) and grow to a length of 3.0 m (10 ft). Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 6.8–15.9 kg (15–35 lb)) at a single feeding. Sea lions can move around 16 knots (30 km/h; 18 mph) in water and at their fastest they can reach a speed of about 30 knots (56 km/h; 35 mph). Three species, the Australian sea lion, the Galápagos sea lion and the New Zealand sea lion, are listed as endangered.
