Yet another dead gray whale has washed ashore in the San Francisco area.
The cetacean is the 13th to be either dead or dying that has come aground Bay Area shores since March, confirmed The Marine Mammal Center on Thursday.
The latest casualty was discovered in Point Reyes National Seashore, reported the San Francisco Chronicle.
More whales have been spotted in San Francisco Bay than usual, and scientists are concerned that it could be a sign of starvation.
When they’re hungry, they can’t complete the full migration from California to Alaska, where they spend the summer. They stop longer during the trek in hopes of finding food to fuel their journey.
A few of the dead whales have shown serious signs of emaciation. Others were likely killed by ship strikes, which could be an indirect result of them staying in heavily congested San Francisco Bay for longer periods than usual.
Research biologist John Calambokidis said a potential cause for the starving animals could be a boost in the gray whale population, which would mean be less food to support them all. But he also believes climate change could be a factor. Weather shifts in the Arctic, including water temperature and ice cover, could be weakening the whales’ food supply.
