In this July 19, 2010 photo released by PRBO/NOAA, shown is a closeup of krill taken in the Gulf of the Farallones National Marine Sanctuary on an ACCESS Ãcruise off the Northern California coast. Whales, including endangered blue whales and humpbacks, have been feeding off plentiful krill off the coast in record numbers in recent years, colliding with large ships coming in and out of San Francisco Bay at higher-than-usual rates. After a two-year study spurred by this spike in whale strikes, federal regulators and the commercial shipping industry have agreed to redirect ship traffic coming out of the bay, and make others slow down when whales are present.
