    Iirc, sardines require cool currents to get through warm(er) water. There’s a thing called the sardine run, where a specific area in the migration path has a (relatively) narrow cold water current that forces them into a bottleneck, and predators feast in a huge spectacle.

    What I’m guessing happened was these poor guys were following a cold current that disappeared, and died of heat exhaustion. Which iirc isn’t that uncommon of an occurrence
