Watch orcas ram a sunfish so hard it explodes

Orcas in the Gulf of California have been observed employing a novel ‘ram-to-fragment’ strategy to break apart dead sunfish. This behavior, filmed on two separate occasions, involves orcas ramming the carcasses with high force, causing them to disintegrate into smaller pieces. Scientists theorize this could be a method to aid younger orcas in feeding, a form of play, or a sophisticated processing technique that is species-specific to the sharp-tail sunfish.

• Orcas in the Gulf of California were filmed using a ‘ram-to-fragment’ strategy on sunfish.
• This behavior involves ramming the sunfish carcass with high force, causing it to explode into fragments.
• The behavior is thought to be a form of social learning, potentially helping younger orcas feed or simply being a form of play.
• This technique differs from typical orca hunting, as the sunfish were already dead and their viscera removed, suggesting it’s a processing method.
• The strategy might be specific to the sharp-tail sunfish, possibly due to its structural response to impact and its tail’s suitability for gripping.
