LOS ANGELES - A stray gray whale has left a shallow marina near Los Angeles after spending more than three weeks there.
Marine biologist Peter Wallerstein said Sunday that he and a county Baywatch crew watched the 25-foot animal yearling head northwest out of Marina Del Rey. He says it was accompanied by about 50 bottlenose dolphins.
Wallerstein says the group lost track of the whale as it swam into the ocean Friday night.
The whale appeared in the shallow manmade marina on June 2 in a detour from its migration from Baja California to Alaska.
The National Marine Fisheries Service appointed a baby sitter last week to watch the whale and protect it from curious onlookers and to see if it would require human intervention.
