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 Dangela was found with his flippers tightly folded against his body. He was brought to our hospital and diagnosed with leptospirosis—a bacterial infection of the kidneys that can be fatal if left untreated.

Dangela was just one of hundreds of California sea lions we’ve treated for leptospirosis during major outbreaks every four or five years. This disease is serious because it can also infect humans and dogs. By treating patients like Dangela, our scientific experts gain a better understanding of how leptospirosis is transmitted and how to protect human health.

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

Once Dangela recovered fully from the disease, he was released back to the wild with a second chance.
