In a disturbing pattern going back to early April, three more dead gray whales have been sighted in the San Francisco Bay in the past week.
The whale carcasses were spotted in Tiburon, the Port of Oakland and Angel Island State Park, but unlike previous whale sightings, none were accessible enough for scientists to determine the cause of death.
Since the beginning of April, four previous gray whale deaths and one fin whale death have been reported in San Francisco Bay, according to the Marine Mammal Center, the Marin County veterinary hospital whose scientists perform necropsies on the large animals. They determined that three of those whales died from ship strike injuries while the cause of death for the other two could not determined.
