SANTA CRUZ — Blue whales, the world's largest animal, are being seen in droves off the Northern California coast.
The ocean giants are being lured by an increase this year in their favorite food — shrimp-like creatures known as krill, biologists said.
In Monterey Bay, whale watching tour operators have reported seeing dozens of blue whales and droves of humpbacks.
Marine biologist Nancy Black told the Santa Cruz Sentinel (http://bit.ly/Ng8lI0) that basking sharks, the world's second-largest shark species, have also made an appearance.
"I tell people it's a once-in-a-lifetime chance," she said.
