Overview
Killer whales (Orcinus orca) have recently stunned researchers with their predation on one of the ocean’s top predators: the great white shark. Using advanced hunting strategies, some orca pods have repeatedly targeted sharks for their nutrient-rich livers, leaving behind corpses with surgical precision.
Notable Events
- South Africa (False Bay): Orcas named Port and Starboard are known for hunting great whites and removing only the liver. Source: Vice
- Australia (Victoria): A 4.7-meter great white found with a 50 cm bite and missing liver was linked to orcas Bent Tip and Ripple. Source: The Guardian
- Gulf of California: Reports of orcas hunting blacktip, bull, and hammerhead sharks show this may be a learned and expanding behavior. Source: LiveScience

How Orcas Kill Sharks
- Tonic Immobility: Flipping sharks upside down induces paralysis.
- Precision Targeting: Orcas bite near the liver and avoid unnecessary damage.
- Organ Preference: The liver is high in squalene and easy energy; other organs are often left untouched, except the testicles and stomachs in some cases.
Ecological Impact
- Shark Displacement: Great whites have abandoned traditional grounds like False Bay.
- Trophic Cascade: Mesopredator boom leads to prey imbalance (e.g., rays increasing in absence of sharks).
- Eco-Tourism Loss: South African shark diving has declined due to fewer shark sightings.

Conclusion
This growing body of evidence confirms that orcas are now actively targeting some of the ocean’s most formidable predators with purpose and precision. As marine ecosystems adapt to these changes, scientists continue to study the ripple effects throughout global food webs.
