Its a pacific sleeper shark, a little known deep sea shark closely related to the Greenland shark.
It can grow to huge sizes (normally 4 meters) but is rarely caught because it lives in deep waters.
The video is from 1990, and the shark was estimated to be 7 meters long, so its large for a sleeper sharks.
Apparently the giant shark was a minor sensation ("sommerloch?") in Japan in 1990 and now made a happy comeback thanks to youtube.
Back then the japanese tabloids made a megalodon out of it. Prof. Eugenie Clark (one of the world's leading shark experts) made the estimate of "23 feet".
Japanese tabloids made 23 meters out of that instead of 7, and so the Sharkzilla was born

23 feet is quite big enough thank you
