Jellyfish Taste for Burrowing Worms Documented for the First Time
A Danish study finds jellyfish from two species feeding on polychaete worms, a burrowing bottom-dweller, marking the first documented instance. Across a year, 45 of 166 Aurelia aurita and 3 of 71 Mnemiopsis leidyi were found with worms in their guts, typically when worms rise to spawn at night. This seasonal feeding burst adds a new layer to fjord energy flow and could affect ecosystems if the invasive M. leidyi expands.
