Herring in the Baltic Sea turns into a predator
Herring, which usually feed on plankton, switched to eating other fish and grew in size.
Scientists have discovered a new population of herring in the Baltic Sea, which feeds on other fish, and not plankton, like other representatives of this species. The scientific journal phys.org reports a new evolutionary leap in a seemingly well-studied fish species.
