Passengers on a boat tour in the Bahamas witnessed a dramatic moment when a daring dog dives from a nearby dock and attempts to jump onto the back of a hammerhead shark.
A violent moment was caught on camera and passengers could be heard screaming and begging the puppy to turn back.
The dog and shark struggled for a few seconds, but the energetic dog escaped unscathed and the shark swam away, much to the relief and applause of the people on the boat.
