What is a shark that is 66 feet wide
I doubt that even any prehistoric sharks were that wide.The largest confirmed individual whale shark had a length of 12.65 meters (41.50 ft) and a weight of more than 21.5 metric tons (47,000 lb).http://en.m.wikipedia.org/wiki/Whale_shark
Are you talking about Jaws, or am I mistaken.
It could be a giant whale shark
A whale shark.
Whale sharks can grow that long. (Not width - length.) Possibly blue whales, too. They're the largest of all the whales, pretty sure.
