I've had friends see the boat and giant teeth of a giant shark attack of a boat in Japan. (Teeth larger than a great white). [I can't find anything about this on the Internet].
In addition, this report from Pakistan seems to suggest that there are large sharks in the deep of the Oceans.
15-TON PREHISTORIC SHARK CAPTURED OFF COAST OF PAKISTAN
Karachi | A giant prehistoric shark previously thought to be extinct for more than 20 million years has been captured by local fishermen off the coast of Pakistan, reports the Islamabad Herald this morning.
The giant creature first thought to be a great white shark was rapidly declared by experts to be an unknown species of shark as it’s great weight and size were unheard of. Analysis of the teeth suggest the shark to be a parent of the Megalodon, an extinct species of shark that lived approximately 28 to 1.5 million years ago, during the Cenozoic Era.
The sea creature that measures an incredible 10.4 meters and weighs an astounding 15.6 tons is the largest living shark ever caught to date, great white sharks reaching an impressive 7 tons at full growth, a size that is no match for this giant prehistoric shark that can reach an imposing 20 meters in length and possibly weight up to 30 tons, depending on estimates.
My question is: Is there evidence to suggest that sharks from prehistoric times live in the deep of the oceans?
