A Study on Orcas Reveals New Insights into Dolphin Hunts
A remarkable confrontation between orcas and dolphins was captured off the coast of Chile in 2023. Researchers observed a female killer whale overpowering a dusky dolphin, followed by other orcas joining in to share the feast. This encounter marks the first documented evidence of orcas from the Humboldt Current system hunting and consuming dusky dolphins, a small coastal species local to South America. This finding sheds light on the elusive orca population, as it has not yet been classified into any known ecotypes, raising important questions regarding their feeding behaviors and habitats within the Pacific Ocean.
