“Killer Sharks: The Attacks of Black December” premieres tonight at 9pm on Discovery Channel’s “Shark Week.”

Discovery’s description of “Killer Sharks” includes references to events in 1957 at a South African resort in which “the white sands are clogged with dead bodies and the sapphire waters are red with blood.” The description goes on to note that the suspect is a single “massive rogue shark with a taste for human flesh.” The disclaimer before the promotional clips for this episode also note that the show contains content that may “disturb viewers.”

In addition to “Killer Sharks,” Discovery will be re-airing the 2007 show “Top Five Eaten Alive” at 8pm, which recounts the stories of five shark attack survivors.
