4 dead gray whales wash up around San Francisco
Four dead gray whales have washed up on the shores of the San Francisco Bay Area in just eight days, prompting fears that the species is under threat from human activity in the area. The whales probably represent just a small fraction of the number dying in the area.
In 2019, 73 dead gray whales were found washed up along the west coast of North America during a six-month period.
Necropsies have revealed that the main causes of death for gray whales are malnutrition due to climate change, entanglement in fishing gear and trauma from ship strikes.
