Description
Hanna Rittinghaus and co-authors present a 2025 study of what two squid species eat in the North Sea. One species has newly built a breeding population there as waters warm, joining a local species. Both may compete for food, so the team compared their diets in two ways.
Fat patterns in tissue, which reflect staple food over time, showed moderate overlap between the species. Stomach contents, which show recent meals, overlapped strongly by a standard niche index. Both squids ate fish of commercial value such as herring and cod, plus crab-like animals. The authors expect rivalry to grow as the newcomer spreads, with more predation between the squids too.
