Whales in San Francisco Bay

Roughly 30 gray whales have been spotted in the Bay this season, many more than is typical. Sadly, there have also been at least 14 deaths this year, which is more than in all of 2024. 

We are investigating to help determine the cause of these deaths. By gaining insights into what is causing these tragedies, we can better understand how to help prevent them.

California sea lion Argus was rescued just a few miles from The Marine Mammal Center near a busy marina. Our veterinary experts determined that he was suffering from leptospirosis, a bacterial infection of the kidneys.

Argus was one of several dozen California sea lions we treated for leptospirosis in 2017, a serious disease that can also infect humans. What our scientists learn from treating patients like Argus helps us better understand how this disease is transmitted and how to protect human health as well.

Treatment for the potentially lethal infection includes antibiotics, fluids and other supportive care, such as gastro-protectants for stomach and intestinal ulcers.

Once Argus had recovered fully from the disease, he was released back to the wild just steps from our hospital.
