It is the tenth dead gray whale since March which has washed up dead on shore in the San Francisco Bay Area. /VCG Photo

Pacifica City workers use a measuring tape to measure the length of the dead whale. The unusually large death toll is reportedly happening because there is too little food to support the giant mammals. /VCG Photo

Necropsies performed on eight of ten whales have determined the reason for the death. Four of the whales died for malnutrition, and four were killed by ship strikes. /VCG Photo
