Entanglement of pinnipeds with plastic debris is an emerging conservation and animal welfare issue worldwide. However, the origins and long-term population level consequences of these entanglements are usually unknown. Plastic entanglement could produce a combination of wounds, asphyxiation, or inability to feed that results in the death of a certain ...

Killer Whales (Orcinus orca) in the Indo‐Pacific: A Review of Their Distribution, Population Structure, and Ecology

Mammal Review, Volume 56, Issue 3, September 2026.
This review synthesises knowledge on killer whales across the Indo‐Pacific through the integration of published studies and collaboration. It shows that variation in killer whale occurrence, diet, and fisheries interactions is shaped by environmental heterogeneity and uneven research effort and highlights knowledge gaps with implications for ...
