[Quiet Man Cometh]

I think the guide on my TV has the shows mangled a little. The show is called "Dangerous Encounters" andn their checking bite force and such of different sharks but they're mentioning something about using a homemade submarine to find sixgills. You can dive for those at the right time of year. Meh. Maybe they want to see them deeper down. Never known six gills to make for dangerous encounters though.
