In its 37th year, Shark Week is the Discovery Channel's annual weeklong slate of shark-related programming. This year's event kicked off Sunday, July 20, with "Dancing With Sharks," an inter-species dance competition hosted by returning "Dancing With the Stars" frontman Tom Bergeron.

Shark Week debuted on the Discovery Channel on July 20 and continues with thrilling programming until Saturday, July 26. Here's how to watch.

Shark Week opens with “Great White Sex Battle.” Watch three consecutive premieres starting at 8 p.m. ET on Discovery.

Discovery Channel’s “Shark Week” kicks off with a unique twist this year: “Dancing with Sharks.” Hosted by former “Dancing With the Stars” host Tom Bergeron, the show features scuba-diving shark handlers performing underwater dances with hammerhead sharks.

Tom Bergeron talks hosting Shark Week's "Dancing With Sharks" and the "sad" trophy. "That's the same reaction I had with the 'DWTS' trophy."
