A new study has revealed that gray whales in San Francisco Bay are facing a growing threat from boat strikes and other human activity, putting the iconic marine mammals at risk despite the end of commercial whaling. Researchers found that the whales' low profile and the region's frequent foggy conditions make them difficult to spot, leading to deadly collisions with vessels.

Why it matters

Gray whales are an important part of the local ecosystem and a major draw for whale watching tours in the San Francisco Bay Area. Their potential decline due to human impacts would be a significant loss for the region's natural heritage and tourism industry.

The details

The study found that gray whales' low profile to the water and the common foggy conditions in San Francisco Bay make them hard for boat operators to see, leading to an increasing number of deadly collisions. In addition, other human activities like pollution and habitat degradation are also taking a toll on the whale population.

  • The new study was published in April 2026.
