Pod of blue whales spotted near Dana Point

A pod of blue whales was spotted off the coast of Dana Point on Friday, and it may be an abundant supply of krill that attracted them.

One of the reasons so many of the whales are hanging out near the Southern California coast is an upwelling of cold ocean water that is creating perfect feeding conditions.

The cold water swirled upward by colliding currents brings with it krill, which are shrimp-like crustaceans that whales feast on.

A pod of blue whales was also seen near La Jolla on Thursday, and last month, one was spotted a few miles from shore in Redondo Beach.

At 100 feet, blue whales are the world's largest mammal - twice as long as gray whales.

Experts say the upwelling could last until the end of the month.
