Shark Week 2013 starts on Discovery Channel at Tonight: Start Time and more. The Discovery Channel’s 26th annual Shark Week begins on Sunday August 4, 2013 in the U.S., with almost round-the-clock documentaries about sharks, including 11 hours of new material. Among the highlights will be a provocative documentary about the extinct giant shark megalodon possibly still lurking the oceans, freshwater bull sharks near New Orleans, a revised top ten sharkdown of the most dangerous shark species, and a look at extremely rare deep sea sharks. Discovery is also introducing a new feature to Shark Week, a live talk show hosted by comedian Josh Wolf called Shark After Dark.
