Harbour Porpoises Are Flexible Predators Displaying Context‐Dependent Foraging Behaviours

Ecology and Evolution, Volume 14, Issue 12, December 2024.
This study provides the first record of previously undescribed foraging behaviours of harbour porpoises. Our results indicate use of context‐dependent foraging strategies, suggesting that porpoises are flexible predators that use conditional foraging strategies and adapt their behaviour in response to environmental characteristics.
