A rare sighting of a pod of orcas off the coast of northern Chile has provided marine biologists with a unique opportunity to study these elusive predators up close. Led by a female orca named Dakota, the pod was observed hunting sea lions near the Chilean bay of Mejillones in 2018, sparking interest and investigation from researchers.
Marine biologist Ana María García Cegarra, from the University of Antofagasta, led a study published in the journal Frontiers in Marine Science, shedding light on the hunting preferences and behaviors of the orcas in the region. Using drones, researchers were able to capture footage of a successful orca hunt of dusky dolphins, providing valuable insights into their feeding habits.
With concerns about pollution, maritime traffic, and collision risks impacting the orca population in the area, conservation efforts are seen as crucial to preserving this little-known species. Despite the challenges of studying these intelligent and agile animals, researchers are optimistic that this study is just the beginning of uncovering the mysteries of orcas in the southern hemisphere.
Pollution and collision risks
Experts like Bruno Díaz and Ricardo Aguilar highlight the need for measures to protect orcas from human impacts and industrial activities in coastal areas. As researchers continue to study these magnificent creatures, the hope remains that conservation efforts will help ensure the survival of the orca population in Chilean waters.
