Drone Study Confirms Gulf of California Orcas Flip Young Great Whites to Eat Their Livers

Researchers say shifting nursery locations linked to warming may be bringing naive juveniles into the pod’s path.

Overview

  • Peer-reviewed findings in Frontiers in Marine Science include new drone videos documenting the behavior in Mexico’s Gulf of California.
  • Two observed hunts in August 2020 and August 2022 resulted in three juvenile great white shark deaths.
  • Orcas induced tonic immobility by flipping the sharks upside down, then removed the nutrient-rich livers.
  • The same group, identified as the Moctezuma pod and known for targeting sharks and rays, was confirmed by unique dorsal-fin features.
  • Scientists hypothesize climate variability, including El Niño, is increasing juvenile shark presence in the area and call for broader diet surveys to assess frequency and potential ecosystem effects.
