This patient presented to the emergency department (ED) with the head of a very large snapping turtle biting down on his left thumb. The patient had caught the turtle, decapitated it, and placed the turtle’s head into a bucket. A short time later, while reaching into the bucket, he accidentally placed his left thumb into the turtle’s mouth, and the turtle head reflexively bit down on his thumb. The patient could not remove the head and presented to the ED for assistance. He was in a mild amount of painful distress.
The decapitated head of a snapping turtle biting down onto the patient’s left thumb
The decapitated turtle head after removal from the thumb
The turtle’s head was clamped down onto the patient’s left thumb. No open wounds were noted.
Tendon or joint injury
The turtle’s head was pried off using two pliers. There were no significant wounds to his finger.
The patient was discharged.
Pliers are yet another tool that the emergency medicine physician should have in the departmental toolbox.
An anecdotal statement was made by this patient that decapitated turtle heads will continue to reflexively bite down for up to 9 days after decapitation. Non–peer-reviewed, online discussions corroborate this postdecapitation reflex.
The force of a turtle bite is dependent on several factors, including the size of the turtle and the shape of the turtle head. Forces of up to 400 N have been observed.
