A gray whale has washed ashore in Northern California, the fifth dead whale found in the Bay Area since March and the third in a week.
The Marine Mammal Center said the whale was discovered Tuesday on Bolinas Beach in Marin County. A necropsy was planned.
Scientists said human-caused injuries killed two whales found last week in the area.
The Marine Mammal Center said a ship hit a 45-foot-long fin whale that was found May 18 near Oakland. A necropsy found the juvenile female had broken bones and massive hemorrhaging. That same day, a second whale carcass was found on Tennessee Valley Beach in Marin County. Authorities say the 36-foot adult female gray whale died after becoming entangled, probably in fishing gear.
