Jessica Radcliffe orca attack video” widely circulating on social media is a hoax; there is no credible evidence that Jessica Radcliffe is a real person or that such an orca attack occurred.

Fact-checking by various sources and investigations found no news reports, official statements, or occupational safety records about this incident or any trainer by that name.
The videos are fabricated or recycled footage accompanied by AI-generated voices and dramatic narration to create a sensational story.This viral story claims that Jessica Radcliffe, an orca trainer, was attacked and killed by a killer whale named Nyx during a marine park performance.

However, no authoritative news outlet or marine park has confirmed such an event, and fact-checkers concluded it is entirely fictional.
The narrative follows a familiar pattern of online misinformation fueled by clickbait and repeated without verification.
