Orcas Explode Fish Into Confetti, Possibly for Fun, In ‘Astounding’ New Video

Scientists have found a beforehand unknown conduct in orcas that entails one member of a pod holding up a large lifeless sunfish whereas one other costs and rams it, ensuing within the dramatic explosion of the carcass into fleshy fragments, in line with a study published on Thursday in Frontiers in Ethology.  

Orcas typically ram or strike prey as a searching tactic, and a few pods are additionally infamous for ramming boats. But the brand new examine is the primary to report such explosive outcomes and sheds gentle on the mysterious lives of orca pods within the Gulf of California. The hold-and-ram technique permits juvenile orcas to feed on smaller chunks of tissue and may function a type of social studying and play in these extremely smart marine mammals. 

Erick Higuera, a wildlife cinematographer and marine biologist, first noticed orcas detonating a sunfish in 2021. The tactic was captured in follow-up footage by marine biologist Kathryn Ayres in 2024, in addition to video from one other occasion in 2025, filmed by Héctor Franz, who works in ecotourism. 

“The first time I witnessed it, at that moment, the energy of the impact was astounding because we could hear the sound when the orca ran into the sunfish,” stated Higuera, who co-authored the brand new examine, in a name with 404 Media. “Seeing a multi-ton predatory mammal striking a massive fish—because sunfishes can go up to two meters depending on the species—with such a fast speed is breathtaking, and immediately we knew that we were witnessing something highly unusual due to the magnitude of the tissue explosion.”

Orcas are social animals that type tight-knit matrilineal pods that in flip belong to broader “ecotypes” with their very own distinctive cultures and ranges. In the Northeastern Pacific, there are three genetically distinct lineages: resident orcas that primarily eat fish, transient orcas that primarily eat marine mammals, and offshore orcas that prey on sharks. 

But much less is thought concerning the feeding behaviors of orcas at decrease latitudes close to the equator, which don’t appear to fall into such clear ecotypes. For years, Higuera and his colleagues have been capturing footage with drones and underwater cameras to raised perceive the mysterious pods that roam within the Gulf of California. That’s how they had been capable of fortuitously seize the explosive hold-and-ram technique on movie. 

Sunfish are giant, however straightforward to hunt, making them a well-liked goal for orcas and different ocean predators. However, these animals have robust and rubbery flesh that’s troublesome to tear aside, particularly for younger orcas. For this cause, Higuera and his colleagues speculate that the ramming method is primarily supposed to loosen nutritious tissue from the carcass for juveniles to eat, noting that the adults centered on consuming organs and meat from the physique itself, leaving the fishy ejecta for his or her younger. The conduct may simply be enjoyable, as orcas typically play with their meals.

“Orcas are highly encephalized predators that frequently engage in object manipulation and play behavior with their prey,” Higuera stated. “That is very globally well known. Because sunfish are slow-moving and defenseless, they present a low-risk opportunity for the pod, especially subadults, so they can practice strike precision and reinforce social bonds. It’s social play and learning.”

The staff plans to proceed monitoring the pod to raised perceive the conduct, and to be taught whether or not the sunfish’s microbiome and enzymes would possibly comprise particular vitamins for the orcas. At the identical time, Higuera emphasised that human interactions with orcas ought to stay as restricted as potential, particularly since whale watching within the area has turn into a well-liked vacationer exercise.  

“This groundbreaking insight was only made possible through a vital collaboration between expert scientists, eco-tourism operators, and citizen scientists equipped with drones and cameras that are willing to provide their footage to us so that we don’t spend that much time in the field,” Higuera stated.

“If we can protect these animals by maintaining a respectful distance,” he concluded, “this ongoing partnership will allow us to safely document hidden mysteries of marine life that would otherwise remain completely closed to science.”
