科学家观察到虎鲸在加州湾（墨西哥沿岸）以极高速度撞击翻车鱼，造成猎物身体碎裂成数千块的现象。1该行为已被记录两次，首次事件发生于2024年7月，第二次则在2025年9月被旅游运营商捕捉。1
被撞击的翻车鱼体型巨大，体长超过3米，重量可达2000公斤。1研究人员对这一现象的含义提出了两种解释。科学家卡瑟琳·艾尔斯表示："我们认为这可能帮助年轻虎鲸更容易进食，或者也可能只是为了好玩。虎鲸以玩耍它们的食物而闻名。"1
这项研究已发表在期刊《Frontiers in Ethology》上。1该发现进一步展示了虎鲸高度的认知能力和复杂的社交行为。此前，墨西哥去年针对与虎鲸一起游泳发布了新规定。1
Scientists have documented orcas striking ocean sunfish with such force that the prey shatters into thousands of pieces 1. Researchers believe this behavior may serve dual purposes: helping younger orcas feed more easily, or simply providing entertainment 1.
"We think this might help young orcas eat more easily, or it could just be for fun," said scientist Catherine Iles, noting that orcas are known for playing with their food 1.
Two such incidents have been recorded in California Bay off the Mexican coast 1. The first ramming was documented in July 2024, with a second event captured by a tour operator in September 2025 1. The sunfish targeted in these attacks exceeded three meters in length and weighed up to 2,000 kilograms 1.
The findings, published in the journal Frontiers in Ethology, highlight the cognitive sophistication and complex social behavior of orcas 1. Mexico issued new regulations last year governing swimming with orcas 1.
