In footage viewed more than a million times online, the crustacean is seen gripping one of its claws before successfully detaching it and fleeing.
The dramatic film was captured by social media user Jiuke, who posted it on the popular Chinese platform Weibo.
Jiuke later told users of the site that he had adopted the crayfish as a pet.
Weibo users had left comments in support of the courageous crayfish, urging "let him go" and "don't eat him, seeing how hard he's trying to survive", the Taiwan News website reported.
Juike then responded: "I let him live, I already took him home and am raising him in an aquarium."
