How a prehistoric salmon survived a volcanic apocalypse
In short: Nearly 2,000 years ago, a volcanic eruption poisoned a salmon's home. This video explores how a specific race of fish survived the disaster and adapted to a perilous new journey to reach their spawning grounds.
Scientists are reconstructing the survival story of a salmon race that faced the destruction of its natal river due to Alaskan volcanic activity. Forced into the open ocean, these fish had to navigate a gauntlet of predators—including sharks, bears, and eagles—while avoiding sulphurous waters.
The narrative highlights a remarkable evolutionary persistence: despite the environmental devastation, the descendants of these pioneers continued to migrate toward the heart of an active volcano to reproduce. It serves as a case study in how species adapt to extreme geological shifts.
