Can anyone give me a list of shark thriller movies?

When I wa sa little kid, I watched a shark movie in which a lot of people in wetsuits including a black guy(just trying to jog the memory) got killed. I want to watch it now since I'm older. But I don't know what's its called. Movies that I know arent it are Deep Blue Sea and the Jaws Series. I think it takes place in an underwater lab becuase I saw hatches in the movie.
