Resumen:
This is the first report of attacks and predation on dolphins by this marine mammal eating group and, to our best knowledge, in all Patagonia.This report may be an indication of the importance of dolphins in the diet of this particular group of killer whales outside the South American sea lion hunting season (February through April). Besides this well-known stranding behavior, virtually nothing is known about the diet of killer whales in Patagonia. Analyzing the movements of the pods, we can get a clear picture of the way this hunting technique is performed by these killer whales. It is a coordinated hunt in which the hunters herd the dolphin towards an individual that finally catches the prey.
