An alligator made a last-ditch attempt for freedom by headbutting a captor in Florida, knocking him out cold.
The feisty gator, which was tied up at the time, was being lifted into the back of a vehicle to be driven away.
It took three men to hoist the 2m (8ft) animal into the back of the pick-up truck.
As the reptile was almost securely stowed away, it suddenly lashed out.
It headbutted one of the animal catchers and knocked him out cold – sending his sunglasses flying off his head in the process.
The alligator was eventually taken away.
