SAN FRANCISCO – Tourists flock to Fisherman’s Wharf for the seafood and the stunning views of San Francisco Bay, but for many visitors, the real stars are the dozens of playful, whiskered sea lions that lounge by the water’s edge, gulping down fish.

Now a series of sea-lion attacks on people in recent months has led experts to warn that the animals are not as cute and cuddly as they appear.

“People should understand these animals are out there not to attack people or humans. But they’re out there to survive for themselves,” said Jim Oswald, a spokesman for the Marine Mammal Center across the Golden Gate Bridge from San Francisco.

In the most frightening of the recent episodes, a rogue sea lion bit 14 swimmers this month and chased 10 more out of the water at San Francisco’s Aquatic Park, a sheltered lagoon near the bay. At least one victim suffered puncture wounds.

Some scientists speculate that the animals’ aggressive behavior is being caused by eating fish contaminated by toxic algae, or by a shortage of food off the coast. But wildlife experts say even healthy sea lions are best left alone.

In Southern California in June, a sea lion charged several people on Manhattan Beach and bit a man before waddling into the water and swimming away. In Berkeley, a woman was hospitalized last spring after a sea lion took a chunk out of her leg.

Last year, a group of sea lions took over a Newport Beach marina and caused a vintage 50-foot yacht to capsize when they boarded it. And a lifeguard in Santa Barbara was bitten three times while swimming off El Capitan State Beach.
