# Orcas filmed smashing giant sunfish into pieces Scientists document for the first time: Orcas use a new method to fragment their prey. - **Source:** [Latest Science News -- ScienceDaily](https://brifing.si/source/0eef8637-6c5b-4e79-8f5b-6c9c6b36cf16) - **Published:** 2026-07-23 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/cb5f474f-63d5-4ba6-86e8-bc7205066d39 ## Orcas' unique hunting technique Researchers documented orcas using a novel method to break giant sunfish into pieces in the Gulf of California. One orca holds the fish while another rams it at high speed, causing the tissue to fragment. This behavior provides new insights into how orcas process their prey. ## Purpose of the fragmentation Scientists suggest two possible reasons for this technique: facilitating feeding for young orcas or simply for play. While orcas are known to play with their food, such an organized strategy has never been observed before. ## Vulnerability of sunfish Sunfish surface to regulate body temperature or remove parasites, making them easy targets for predators like orcas. These fish can grow up to three meters long and weigh 2,000 kg, making them a frequent prey for orcas in the region. ## Teamwork in hunting In both observed events, orcas worked in coordination. One held the fish steady while another rammed it at high speed, causing fragmentation. This strategy makes it easier to process the prey and helps juveniles feed. ## Microbiome interaction Sunfish have a gelatinous outer layer and skin containing a distinct microbiome. When fragmented, these microorganisms disperse into the water, altering nutrient composition. This may provide nutritional or immune-regulatory benefits to orcas. ## New insights into marine ecosystems This discovery raises new questions about orca hunting strategies and marine ecosystem interactions. Scientists plan to investigate the prevalence and reasons behind this behavior with more high-quality footage. ## Sources covering this story - https://www.sciencedaily.com/releases/2026/07/260723084040.htm — --- _Summary written by Brifing from the original reporting.
