A Hudson woman is behind bars after deputies said she bit off a chunk of her boyfriend's ear during an argument.



Joanie Clark, 31, is facing charges of aggravated domestic battery.



Deputies said Clark was arguing with her live-in boyfriend at their home when things took a violent turn.



At some point during the fight, Clark bit off half the man's ear, deputies said.



When help arrived at the scene, deputies said Clark readily admitted to doing it, but said it was in self-defense.



However, deputies said Clark had no injuries.



Clark was booked into the Land O' Lakes Detention Center. She remains in jail on $5,000 bond.
