Fish in Greenland consume more jellyfish than previously assumed

[Still Waters]

For a long time, scientists assumed that jellyfish were a dead-end food source for predatory fish. However, a team from the Alfred Wegener Institute together with the Thünen Institute has now discovered that fish in Greenland waters do indeed feed on jellyfish.

In two of the analyzed species, they even made up the majority of the food source, as the researchers describe in a study published in the journal Royal Society Open Science.

The results suggest that the role of jellyfish as prey in marine food webs should be reconsidered, especially since they could be profiting from climate change and spreading farther and farther north.
