Prehistoric Shark? (vid)

[Dizaster]

I was just looking at octopuses on youtube and I found this one of a prehistoric shark that was found.. I hadn't seen this before, but most likely someone has posted this vid here before.... Do you personally believe there are a lot of these types of creatures still lurking out there that we havn't seen??
I downloaded some Monster Quest last night and I would love for some really good reputable camera work catch a big weird wonderful creature..

But this shark is pretty freaky..

DUH... I'm no biologist and even I know that a hardy Great White can't be kept in captivity.. Biologists have yet to permanently keep one in captivity as they don't feed properly and die for whatever reason. Stress, lack of food..
But such is human nature to see something nice, attempt to "take" it as their own, and taint or destroy it with their hand..
