A video of a giant sturgeon biting a caretaker's arm during a feeding demonstration has gone viral on social media [1].
The footage highlights the unpredictable nature of large aquatic species and has drawn global attention to the Shibetsu Salmon Science Museum's unique interactive exhibits in Hokkaido, Japan.
The video, which has amassed approximately 60 million views [1], shows a sturgeon suddenly clamping down on the arm of a staff member. The demonstration is part of an attraction at the museum located in Shibetsu Town. According to museum officials, the "arm-bite" show is available through May 6, 2026, marking the final day of Golden Week [2].
Director Masaki Ichimura said that the experience can be painful. He said that different fish have different habits, and some sturgeons twist after biting, which makes the experience more unpleasant.
While the arm-bite demonstration is designed for entertainment and education, the museum also provides a safer alternative for visitors. The facility offers a "finger-poke" experience, which allows guests to interact with the fish in a more controlled manner [2].
Ichimura said the finger-poke experience was established in 2008 [2]. He said that the museum was likely the first in the world to create such a corner, and that no injuries have been reported from the finger-poke activity to date [2].
The museum uses these interactions to educate the public about sturgeons and their behaviors. While the fish do not have teeth, the pressure from their jaws can still cause significant discomfort for the handlers during the more aggressive demonstrations.
“The video, which has amassed approximately 60 million views, shows a sturgeon suddenly clamping down on the arm of a staff member.”
The viral success of the video demonstrates a continuing public fascination with 'animal unpredictability' content. By balancing high-impact demonstrations like the arm-bite show with safer, long-term programs like the finger-poke experience, the Shibetsu Salmon Science Museum leverages social media visibility to drive tourism and educational engagement during peak Japanese holiday periods.
