This is the moment an aggressive swordfish snagged on a fishing line tried to attack scuba divers off the coast of Chumphon, southern Thailand on Friday 13 December.
Footage from one of the crew on a fishing boat shows how the swordfish swam frantically through the water after it was snagged on a hook.
The fish was seen approaching the swimmers, lunging at them in an apparent attempt to pierce its sharp mouth into them, but it was pulled away by the fisherman before it could cause any injuries.
The fish was finally able to win the tussle as it tore the fishing line then swam away.
Being pierced by the sharp nose of a swordfish is potentially deadly.
