A research team has told how they were shocked to find what appeared to be an extinct 50 feet shark, weighing 40 tonnes on a scan under their boat.
The scientists from the Atlantic Shark Institute saw a massive red shape appear on their underwater movement detector which led them to believe that they could have come across a megalodon - a shark that that has been extinct for three million years.
For several minutes they were hooked on the image but then suddenly the apparent red creature began to scatter into thousands of small fish.
