This is the stunning moment that visitors at an aquarium witnessed a bizarre event as one shark bit the fin of another in what appeared to be an aggressive interaction.

On December 10, 2024, in Hainan, Sanya, the video captured a shark was seen clenching onto the fin of another shark, swirling around in an unusual display of behavior.

Aquarium staff later explained that such actions were typical during their breeding season and were not a cause for concern.

This behavior was part of the natural reproductive process among sharks, where biting could be a form of communication or interaction.

The video ended with both sharks swimming away seemingly unharmed, leaving viewers with a glimpse into the complex behaviors of marine life.
