Apr. 13, 2026 -Nearly one-fifth of the gray whales that swam into the San Francisco Bay in recent years died there, mostly after colliding with ships, according to new research published on Monday.
The study estimated that 18 percent of the whales that entered the Bay from 2018 to 2025 did not survive. And among those that died, at least 40 percent had sustained lethal injuries from ship strikes.
In reality, the number of deaths is quite likely higher, the study’s authors and other experts said.
