Rapid predator-prey balance shift follows critical-population-density transmission between cod and capelin https://www.nature.com/articles/s42003-024-06952-6

Oceanographers record the largest predation event ever observed in the ocean

There is power in numbers, or so the saying goes. But in the ocean, scientists are finding that fish that group together don't necessarily survive together. In some cases, the more fish there are, the larger a target they make for predators.

@animalculum wow that is incredible! It boggles my mind to have 10s of millions of fish making massive shoals, which are chased by similarly massive shoals of predator fish. It is really neat that they can resolve individual fish with sonar over a large area.
