Orca Hunting Techniques on Sevengill Sharks

Ingrid Visser and Keniscolet explore the hunting patterns of orcas in New Zealand, focusing on their predation of sevengill sharks. The orcas exhibit precise hunting techniques, targeting the sharks' livers. Despite being a new prey, sevengill sharks have developed defense mechanisms. Ingrid captures rare footage of these interactions, highlighting the orcas' hunting precision.
