Overview

• Wildlife officials have responded to nine whale deaths in the Bay Area in 2025, including eight gray whales and one minke whale.
• The latest casualty, a 39-foot adult female gray whale, was found near Mare Island with injuries consistent with a propeller strike.
• The whale's location and advanced decomposition prevent a necropsy, complicating efforts to confirm the cause of death definitively.
• Thirty gray whales have been identified in the San Francisco Bay this year, a significant increase from just four in 2024.
• Experts urge boaters to exercise caution and encourage the public to report whale sightings through the WhaleAlert app or The Marine Mammal Center's website.
